Paper Trading
When to Use
- Validate a strategy before going live
- Experiment with order sizing and timing
- Teach/demo cdcx without risking funds
- Regression-test an agent's trading behaviour
CLI-only. Paper trading has no MCP tools — agents that need to paper trade must shell out to cdcx paper directly.
Engine
The paper engine is local (no API calls for order state — only for market prices). State lives in ~/.local/share/cdcx/paper/paper_account.json.
Fills use live mark prices fetched from the REST API at the moment the order is evaluated:
- MARKET orders fill immediately at the current ticker price
- LIMIT orders sit and fill when the market crosses the limit
Commands
| Command | Purpose |
|---|
cdcx paper init --balance <n> | Create a new paper account (default 10000 USDT) |
cdcx paper buy <INSTRUMENT> --quantity <q> [--price <p>] | Buy (market if no price) |
cdcx paper sell <INSTRUMENT> --quantity <q> [--price <p>] | Sell |
cdcx paper positions | Open positions with unrealized P&L |
cdcx paper balance | Cash balance + realized P&L |
cdcx paper history | Fills log |
cdcx paper reset --balance <n> | Wipe state and start fresh |
All commands support -o json, -o table, -o ndjson.
Workflow
Bootstrap
cdcx paper init --balance 50000
cdcx paper balance -o json
Market Trade (round trip)
# 1. Check current price
cdcx market ticker BTC_USDT -o json
# 2. Paper buy
cdcx paper buy BTC_USDT --quantity 0.01 -o json
# 3. Inspect open position
cdcx paper positions -o json
# 4. Close
cdcx paper sell BTC_USDT --quantity 0.01 -o json
# 5. Realized P&L shows up in balance
cdcx paper balance -o json
Limit Order (patient entry)
cdcx paper buy BTC_USDT --quantity 0.1 --price 49000 -o json
The limit sits in the paper engine until the market ticker crosses 49000. Check back with cdcx paper positions — until filled, the cash is reserved.
Strategy Backtest Loop
# Bootstrap
cdcx paper init --balance 100000
# Loop (external script / agent):
# 1. Read signal from cdcx market ticker / candlestick
# 2. Issue cdcx paper buy or cdcx paper sell accordingly
# 3. Call cdcx paper positions -o json to track running P&L
# Review
cdcx paper history -o json
cdcx paper balance -o json
Reset Between Runs
cdcx paper reset --balance 100000
Wipes all positions, trades, and P&L; starts fresh with the specified balance.
Notes
- Paper state persists across
cdcx invocations — use reset to start fresh
- No fees are deducted by default — add them in your strategy if you want realism
- Live streaming ticker is not wired into the paper engine; orders are evaluated on subsequent
cdcx paper invocations using the then-current REST ticker
- For an interactive paper experience use
cdcx tui and press p to toggle LIVE/PAPER mode
