mt5-httpapi

name	mt5-httpapi
description	HTTP client for a user-deployed mt5-httpapi MetaTrader 5 bridge. Use ONLY when the user has explicitly installed and configured mt5-httpapi AND provided MT5_API_URL. Read endpoints (account, symbols, rates, ticks, server-side technical-analysis enrichment via the wickworks sidecar, history, backtest report fetching) are safe to invoke. Trade-mutating endpoints (POST/PUT/DELETE on /orders and /positions, /terminal/restart, /terminal/shutdown) MUST require explicit per-action user confirmation showing symbol, side, volume, and SL/TP — never invoke them on inferred intent. Do not use this skill for generic market-data, charting, or trading questions where the user hasn't named mt5-httpapi.
compatibility	Requires curl and a user-deployed mt5-httpapi instance. MT5_API_URL env var must be set by the user. MT5_API_TOKEN is required whenever the server has auth configured; the agent must obtain it from MT5_API_TOKEN env var OR by asking the user — never by reading repository config files autonomously.

mt5-httpapi

REST client for an MT5 HTTP bridge that the user has already deployed. This skill talks to a running mt5-httpapi server — it does not stand one up, does not provision broker credentials, and does not place trades on its own initiative.

Live Trading Safety — read first

This API can move real money on a user-owned brokerage account. Treat trade-mutating endpoints as irreversible side effects.

Hard rules — never violate, even on user prompts that sound permissive:

1. Per-action confirmation for every mutating call. Before any POST /orders, PUT /orders/<id>, DELETE /orders/<id>, PUT /positions/<id>, DELETE /positions/<id>, POST /terminal/restart, or POST /terminal/shutdown: print the resolved request — symbol, side, volume, SL, TP, price, account login, broker URL — and wait for an explicit confirmation from the user for that specific action. A prior "yes" does not authorize subsequent actions.
2. Demo accounts first. If GET /account shows trade_mode indicating a live account, surface that to the user before any order call and ask them to confirm they intend to trade live.
3. No credential harvesting. Read MT5_API_TOKEN only from the environment variable the user set, or ask the user. Never read tokens, passwords, server names, or login numbers from config/config.yaml, .env, or any other repository file on your own initiative. If the env var is missing, ask the user — do not search the workspace.
4. No mass action. If the user asks to "close everything" or "cancel all", enumerate the affected positions/orders first, show the list, and confirm the whole batch explicitly.
5. Surface broker URL on every mutating action. The path prefix /<broker>/<account>/ in MT5_API_URL determines which real account is touched. Show it in confirmation prompts so the user can catch a wrong-account misroute.

Read-only endpoints (GET /account, GET /symbols/*, GET /symbols/*/rates, GET /symbols/*/ticks, POST /symbols/*/rates/ta, GET /positions, GET /orders, GET /history/*, GET /backtest/*, GET /terminal, GET /ping) do not require per-action confirmation.

One-stop technical analysis. Skip the client-side TA stack entirely. POST /symbols/<symbol>/rates/ta with an indicator spec → get OHLC bars + analyzed indicator series back in a single call. RSI, MACD, Bollinger, ADX, ATR, VWAP, Ichimoku, Order Blocks, Fair Value Gaps, BOS/CHoCH, swing structure, S/R levels, liquidity, session anchors, dozens more — all computed server-side by the wickworks sidecar that ships with this stack. Primitives only — wickworks returns raw indicator series and structural facts (e.g. "order block formed at this bar", "price closed past this swing"), never interpretive signals like divergences or crossover events. Build those in the consumer. See the Technical Analysis section.

For installation and setup, see references/setup.md.

Setup

The user must have a running mt5-httpapi instance and must provide:

export MT5_API_URL=http://localhost:8888/<broker>/<account>
export MT5_API_TOKEN=<the-token-the-user-gives-you>

If MT5_API_URL is not set in the environment, ask the user — do not try to discover it from project files. Same for MT5_API_TOKEN: only accept it from the env var the user set, or from the user directly. Never read it from config/config.yaml, .env, or any other file in the workspace.

A single nginx sidecar (default 127.0.0.1:8888) fronts every terminal. The path prefix /<broker>/<account>/ (matching an entry in terminals.json) selects which terminal you talk to — set MT5_API_URL to the full base including that prefix. Override the host port with API_HOST_PORT=... at compose time.

Verify: curl -H "Authorization: Bearer $MT5_API_TOKEN" $MT5_API_URL/ping — should return {"status": "ok"}. If not, the API isn't up yet (may still be initializing — it retries in the background).

Auth is optional server-side — if no token is configured on the server, all requests go through without a token. If a token is configured, all endpoints require Authorization: Bearer <token> and return 401 without it. From the agent's side, never assume the server is auth-disabled; always pass the token the user provided if there is one.

How It Works

GET for reading, POST for creating, PUT for modifying, DELETE for closing/canceling. All bodies are JSON.

Every error response:

{"error": "description of what went wrong"}

Pre-Trade Checks (DO NOT SKIP)

Before placing any trade:

1. GET /account → trade_allowed must be true
2. GET /symbols/SYMBOL → trade_mode must be 4 (full trading)
3. GET /symbols/SYMBOL → check trade_contract_size — 1 lot of EURUSD = 100,000 EUR, not 1 EUR
4. GET /terminal → connected must be true

API Reference

Health

curl -H "Authorization: Bearer $MT5_API_TOKEN" $MT5_API_URL/ping
# {"status": "ok"}

curl -H "Authorization: Bearer $MT5_API_TOKEN" $MT5_API_URL/error
# {"code": 1, "message": "Success"}

Terminal

curl -H "Authorization: Bearer $MT5_API_TOKEN" $MT5_API_URL/terminal
curl -X POST -H "Authorization: Bearer $MT5_API_TOKEN" $MT5_API_URL/terminal/init
curl -X POST -H "Authorization: Bearer $MT5_API_TOKEN" $MT5_API_URL/terminal/shutdown
curl -X POST -H "Authorization: Bearer $MT5_API_TOKEN" $MT5_API_URL/terminal/restart

Key fields on /terminal: connected, trade_allowed, build, company, broker_utc_offset_hours (signed offset applied to all timestamps in/out — see Broker time below).

Broker time vs real UTC

MT5 returns timestamps in the broker server's wall-clock time disguised as unix integers (RoboForex/FTMO = UTC+3, TeleTrade = UTC+2, etc.). The API normalizes this when utc_offset is set per terminal in config/config.yaml:

terminals:
  - broker: roboforex
    account: main
    port: 6542
    utc_offset: "3h"

(port is container-internal — only nginx and the mt5 container talk to it.)

Forms accepted: "3h", "3h30m", "-2h", "90m", or a bare number (interpreted as hours).

When set, every outgoing time field (tick time, rate time, position/order/deal time* and time_*_msc) is real UTC unix, and every incoming from/to query param is interpreted as real UTC unix. If unset or 0, raw broker timestamps pass through (legacy behavior). Check GET /terminal → broker_utc_offset_hours to confirm.

Account

curl -H "Authorization: Bearer $MT5_API_TOKEN" $MT5_API_URL/account

{
    "login": 12345678,
    "balance": 10000.0,

Timeframes: M1 M2 M3 M4 M5 M6 M10 M12 M15 M20 M30 H1 H2 H3 H4 H6 H8 H12 D1 W1 MN1

Rates/ticks query model — two modes, mutually exclusive:

• Anchor + signed count: count=N = N forward from from, count=-N = \|N\| ending at from, count=0 = empty. Omit from to anchor at now.
• Range (from + to): all bars/ticks in the window, no count cap beyond terminal_info().maxbars. to requires from and rejects count (returns 400).

from and to accept three formats (all real UTC): unix seconds (1700000000), full datetime YYYY_MM_DD_HH_MM_SS (2024_01_15_14_30_00), or date-only YYYY_MM_DD (midnight UTC).

Capped at terminal_info().maxbars rows per request (default 100k — see GET /terminal). Symbols auto-select into MarketWatch on first access. Responses are gzipped if the client requests it (curl --compressed).

Tick flags param: ALL (default), INFO (bid/ask only — ~10× smaller), TRADE (trades only).

Key symbol fields: bid, ask, digits, point, trade_contract_size, trade_tick_value, trade_tick_size, volume_min, volume_max, volume_step, spread, swap_long, swap_short, trade_stops_level, trade_mode.

Technical Analysis

POST /symbols/<symbol>/rates/ta — same query params as /rates (timeframe, count, from, to), JSON body carries the wickworks indicator spec. Response is {symbol, timeframe, bars, ta} — OHLC bars and analyzed indicator series in one round-trip. No client-side TA library needed.

Full catalog with all indicator types, params, output shapes, and SMC primitives is documented at github.com/psyb0t/docker-wickworks.

# RSI + MACD + Bollinger Bands on the last 200 H1 bars; tail TA results to last 50.
curl -X POST -H "Authorization: Bearer $MT5_API_TOKEN" \
  -H 'Content-Type: application/json' \
  -d '{
    "indicators": {
      "rsi": true,
      "macd": true,
      "bbands": {"length": 20, "std": 2}
    },
    "recentBars": 50
  }' \
  "$MT5_API_URL/symbols/EURUSD/rates/ta?timeframe=H1&count=200"

Response shape (keys under ta mirror the keys in your indicators object):

{
  "symbol": "EURUSD",
  "timeframe": "H1",
  "bars": [ { "time": ..., "open": ..., "high": ..., "low": ..., "close": ..., "tick_volume": ... } ],
  "ta": {
    "rsi": [null, null, ..., 54.2, 56.1, 58.7],
    "macd": { "macd": [...], "signal": [...], "hist": [...] },
    "bbands": { "upper": [...], "middle": [...], "lower": [...] }
  }
}

Indicator catalog (request as "name": true for defaults, or "name": {"length": 21, ...} for tuning — params are flat on the object; add "type": "<name>" only when the output key differs from the indicator name, e.g. running two RSIs as rsi14 + rsi21):

• Moving averages: ema, sma, hma, wma, dema, tema, t3, kama, alma, linreg, jma, zlma, rma, fwma, swma, sinwma, trima, vwma, vwap (session-anchored: anchor D/W/M + sessionOffset)
• Momentum oscillators: rsi, mfi, willr, cci, roc, mom, uo, stoch, stochrsi, macd, tsi, trix, fisher
• Trend strength & cross-direction: adx, aroon, vortex
• Volatility: atr, natr
• Volume / money flow: obv, ad, cmf, adosc, kvo
• Bands & channels: bbands, kc, donchian
• Trailing trend signals: supertrend, psar, chandelierExit, ichimoku
• Compression: squeeze (Bollinger inside Keltner — state machine on/off/no flags)
• SMC primitives: orderBlocks, fvg (alias fvgs), bosChoch, swingLevels, srLevels, recentRange, liquidity, previousHighLow, sessions, retracements
• Analysis summaries (last-bar snapshots, shared cached pass — free if you ask for any): price, levels, momentum, volume, position, slope

Wickworks is primitives-only as of v0.3.0 — no built-in divergence detection, no MA-cross events, no golden/death-cross tagging. Build those in the consumer over the raw series.

Each indicator declares its minimum bar requirement (e.g. sma(200) needs 200 bars). If you under-feed it, the server returns HTTP 502 wrapping a wickworks 400 with a per-indicator deficit list — so you see exactly which indicators need more bars, not just a generic "insufficient bars" error.

Pre-flight tips:

• Match count to your slowest indicator's lookback × 2 (e.g. sma(200) → fetch at least 400 bars for warmup + signal).
• recentBars is inert in wickworks v0.3.0 — accepted by the request schema but currently unused (reserved for future signal-tagged outputs). To get only the last N bars, set count accordingly on the rates query, or slice the response client-side.
• Combine with /symbols/:symbol/rates (raw OHLC) when you need TA for charting separate from trade-decision logic.

Orders

Mutating endpoints — confirmation required. Every POST /orders, PUT /orders/<id>, and DELETE /orders/<id> opens, modifies, or cancels a real order on the user's brokerage account. Before invoking any of them you MUST: (1) print the full resolved request (account login from GET /account, broker URL prefix, symbol, side, volume, price, SL, TP); (2) ask the user to confirm that specific action; (3) wait for an explicit yes. A prior confirmation does not carry over to a new action.

# Place market order — only after explicit per-action confirmation from the user.
curl -X POST -H "Authorization: Bearer $MT5_API_TOKEN" $MT5_API_URL/orders \
  -H 'Content-Type: application/json' \
  -d '{"symbol": "EURUSD", "type": "BUY", "volume": 0.1, "sl": 1.08, "tp": 1.10}'

# List pending orders
curl -H "Authorization: Bearer $MT5_API_TOKEN" $MT5_API_URL/orders
curl -H "Authorization: Bearer $MT5_API_TOKEN" "$MT5_API_URL/orders?symbol=EURUSD"
curl -H "Authorization: Bearer $MT5_API_TOKEN" $MT5_API_URL/orders/42094812

# Modify pending order
curl -X PUT -H "Authorization: Bearer $MT5_API_TOKEN" $MT5_API_URL/orders/42094812 \
  -H 'Content-Type: application/json' \
  -d '{"price": 1.09, "sl": 1.07, "tp": 1.11}'

# Cancel pending order
curl -X DELETE -H "Authorization: Bearer $MT5_API_TOKEN" $MT5_API_URL/orders/42094812

Order types: BUY, SELL, BUY_LIMIT, SELL_LIMIT, BUY_STOP, SELL_STOP, BUY_STOP_LIMIT, SELL_STOP_LIMIT

Fill policies: FOK, IOC (default), RETURN

Expiration: GTC (default), DAY, SPECIFIED, SPECIFIED_DAY

Required fields: symbol, type, volume. price auto-fills for market orders.

Trade result:

{
    "retcode": 10009,
    "deal": 40536203,
    "order": 42094820,
    "volume": 0.1,
    "price": 1.0950,
    "comment": "Request executed"
}

retcode 10009 = success. Anything else = something went wrong.

Positions

Mutating endpoints — confirmation required. PUT /positions/<id> changes the SL/TP of a live position, and DELETE /positions/<id> closes it (full or partial). Both move real money. Per-action confirmation rule above applies — print symbol, ticket, current price, the change being made, and wait for explicit user yes.

curl -H "Authorization: Bearer $MT5_API_TOKEN" $MT5_API_URL/positions
curl -H "Authorization: Bearer $MT5_API_TOKEN" "$MT5_API_URL/positions?symbol=EURUSD"
curl -H "Authorization: Bearer $MT5_API_TOKEN" $MT5_API_URL/positions/42094820

# Update SL/TP
curl -X PUT -H "Authorization: Bearer $MT5_API_TOKEN" $MT5_API_URL/positions/42094820 \
  -H 'Content-Type: application/json' \
  -d '{"sl": 1.085, "tp": 1.105}'

# Close full position
curl -X DELETE -H "Authorization: Bearer $MT5_API_TOKEN" $MT5_API_URL/positions/42094820

# Partial close
curl -X DELETE -H "Authorization: Bearer $MT5_API_TOKEN" $MT5_API_URL/positions/42094820 \
  -H 'Content-Type: application/json' \
  -d '{"volume": 0.05}'

Key position fields: ticket, type (0=buy, 1=sell), volume, price_open, price_current, sl, tp, profit, swap.

History

curl -H "Authorization: Bearer $MT5_API_TOKEN" "$MT5_API_URL/history/orders?from=$(date -d '1 day ago' +%s)&to=$(date +%s)"
curl -H "Authorization: Bearer $MT5_API_TOKEN" "$MT5_API_URL/history/deals?from=$(date -d '1 day ago' +%s)&to=$(date +%s)"

from and to are required, unix epoch seconds.

Deal fields: type (0=buy, 1=sell), entry (0=opening, 1=closing), profit (0 for entries, realized P&L for exits).

Backtest

Run MT5 Strategy Tester via the API. Two-stage workflow: build the INI from a JSON spec, then submit it together with the .ex5 (and optional .set) for async execution. Endpoints exist on every terminal but only run on a mode: backtest terminal in config.yaml — MT5 is single-instance per portable data dir, so a tester subprocess collides with a mode: live terminal that already owns the directory and exits silently. The broker/account in the URL determines which credentials are injected into the run's [Common] section. Only one tester runs at a time per API process; extra submissions queue.

The expert and set file can be uploaded inline OR referenced by name from a host-managed pool mounted at assets/experts/*.ex5 and assets/sets/*.set.

# 1. Build INI: NZDJPY M15, last 5 years, open prices only, 5 ms latency.
curl -sS -X POST -H "Authorization: Bearer $MT5_API_TOKEN" \
  -H "Content-Type: application/json" \
  $MT5_API_URL/backtest/build-ini \
  -d '{
    "symbol": "NZDJPY",

    "latencyMs": 5,
    "expertParameters": "ea studio nzdjpy m15 1615044595.set"
  }' > tester.ini

  | jq -r .jobId)

# 3. Poll. Status is queued → running → completed (or failed).
curl -H "Authorization: Bearer $MT5_API_TOKEN" $MT5_API_URL/backtest/$JOB

# 4. Fetch the report HTML and the terminal log.
curl -H "Authorization: Bearer $MT5_API_TOKEN" $MT5_API_URL/backtest/$JOB/report -o report.htm
curl -H "Authorization: Bearer $MT5_API_TOKEN" $MT5_API_URL/backtest/$JOB/log    -o run.log

POST /backtest/build-ini JSON fields: symbol, timeframe (M1…MN1), expert (must end .ex5), and exactly one of fromDate+toDate, lastYears, or lastDays. Optional: modelling (every-tick 1m-ohlc open-prices real-ticks), latencyMs, deposit (10000), currency (USD), leverage (100, written as 1:N), expertParameters (.set), reportName (backtest-report.htm).

POST /backtest multipart fields: ini (required), one of expert or expert_name, optional set or set_name. Returns 202 with jobId, statusUrl, reportUrl, logUrl, pollAfterSeconds, queuePosition. The INI's [Common] Login/Password/Server are always overwritten with the URL-selected account's credentials. Path traversal in *_name is rejected.

GET /backtest/<jobId> returns the job state. When status: completed, the payload includes a summary parsed from the HTML (netProfit, profitFactor, recoveryFactor, expectedPayoff, sharpeRatio, maxDrawdown, totalTrades, profitTrades, lossTrades, …). Jobs left running when the API restarts are marked failed on the next startup.

Real Backtest Runbook For Agents

When the user asks for a real backtest run, do not stop at a built INI or a 202 Accepted submit response. The task is only complete after one of these is true:

• the job reaches completed, the report/log are downloaded, and the requested summary fields are returned
• a request fails and you report the exact endpoint, HTTP status, and response body
• the job reaches failed and you report the final status payload exactly

Before submitting a backtest that references host-managed files:

1. Verify the requested filenames exist on disk exactly as named under assets/experts/ and assets/sets/.
2. Verify GET $MT5_API_URL/ping returns backtest mode on the target terminal. For a real tester run, expect {"status":"ok","mode":"backtest"}.
3. If the user specifies a concrete date window, prefer explicit UTC fromDate/toDate and do not also send lastYears or lastDays.
4. Auth handling: use MT5_API_TOKEN from the user-set environment variable. If it is missing and the server requires auth, ask the user to provide it — do not search the repository or read config/config.yaml to harvest credentials. Backtests are read-side from the user's perspective (the server orchestrates Strategy Tester locally and never opens live trades), so no per-action confirmation is required to submit, but still surface the broker URL prefix so the user can catch a wrong-account misroute.

Execution guidance:

• Prefer one shell script or one tightly scoped command sequence that performs verify -> ping -> build INI -> submit -> poll -> download artifacts. This reduces uncertainty from partially completed attempts.
• Persist the local artifacts in a dedicated output directory: tester.ini, status.json, report.html (or .htm), and run.log.
• Treat queued and running as normal intermediate states. Report the job ID and latest status while polling.
• If no jobId has been captured yet, there is no confirmed backtest in progress. Do not claim the server is still working without that evidence.
• Poll GET /backtest/<jobId> using pollAfterSeconds from the submit/status payload when available. If the user explicitly requests a cadence, follow it.
• On any non-2xx HTTP response, stop immediately and show: endpoint, HTTP status, and raw response body.
• On status: failed, stop immediately and show the full final status payload.

Completion guidance:

• Download both reportUrl and logUrl before declaring success.
• Return the requested summary fields directly from the final status payload's summary object.
• Include the local artifact paths so the user can inspect the exact report and terminal log.

Example agent-oriented flow:

# 0. Verify host-managed assets exactly as named.
test -f "assets/experts/EA.ex5"

Position Sizing

risk_amount     = balance * risk_pct
sl_distance     = ATR * multiplier
ticks_in_sl     = sl_distance / trade_tick_size
risk_per_lot    = ticks_in_sl * trade_tick_value
volume          = risk_amount / risk_per_lot

Round down to nearest volume_step, clamp to [volume_min, volume_max]. Sanity check: volume * trade_contract_size * price should make sense relative to account balance.

Tips

• Always check retcode — 10009 = good, anything else = bad
• Use GET /error to debug failed trades
• deviation on orders = max slippage in points (default 20, raise for volatile markets)
• type_filling matters — try FOK, IOC, RETURN if orders get rejected
• Candle time is the open time, not close time
• trade_stops_level = minimum SL/TP distance from current price in points
• Markets have hours — check trade_mode before placing orders
