description	Dollar Cost Averaging (DCA) strategy for periodic Bitcoin or RGB asset purchases. Use when running a scheduled DCA loop: get the current rate, optionally apply price-aware logic (skip on pumps, buy on dips), then execute a fixed-size swap. Requires kaleido-mcp.

DCA (Dollar Cost Averaging) Skill

You run periodic, fixed-size purchases of a target asset to build a position over time regardless of price. Buy a fixed USDT amount on a schedule — this averages your cost basis over market cycles.

Configuration (read from context or config block)

{
  "enabled": true,
  "target_asset": "BTC",
  "source_asset": "USDT",
  "amount_usdt": 10.0,
  "interval_sec": 86400,
  "price_aware": {
    "enabled": false,
    "skip_if_rate_above_ema_pct": 5,
    "double_if_rate_below_ema_pct": 10
  },
  "dry_run": true
}

Step 1: Check if DCA is Enabled

If enabled: false → exit with "action": "disabled".

Step 2: Get Current Rate

Use kaleidoswap_get_quote to get the live BTC/USDT rate:

kaleidoswap_get_assets()   → resolve USDT asset_id and precisions

kaleidoswap_get_quote({
  from_asset_id: "BTC", from_layer: "BTC_LN", from_amount: 100000,
  to_asset_id: "<USDT_ID>", to_layer: "RGB_LN"
})
→ rate = (to_amount / 10^usdt_precision) / (100000 / 1e8)
  e.g. 95000.00 USDT/BTC

This is the price we'll actually trade at.

Step 3: Price-Aware Logic (optional)

If price_aware.enabled: true, compare current rate to an internally tracked exponential moving average (EMA) maintained across runs in agent state.

if rate > ema × (1 + skip_if_rate_above_ema_pct / 100):
    → skip this cycle: "rate above EMA threshold"

if rate < ema × (1 - double_if_rate_below_ema_pct / 100):
    → double the amount: amount_usdt × 2  (buy the dip)

Update EMA after each run: ema = ema × 0.9 + rate × 0.1

If price_aware.enabled: false → always use configured amount_usdt.

Step 4: Check Available Funds

rln_get_balances()

Compute USDT balance. If usdt_balance < amount_usdt: → exit with "action": "skipped", "reason": "insufficient USDT"

Step 5: Execute the Purchase

1. Convert amount_usdt to raw USDT units: amount_usdt × 10^usdt_precision
2. kaleidoswap_get_quote({ from: USDT, to: BTC, amount: raw_usdt })
3. Execute atomic swap (see kaleidoswap skill)
4. Poll until status: "completed" or "failed"

If dry_run: true → describe the trade and log the report; do NOT execute.

Step 6: Output Report

{
  "loop": "dca",
  "timestamp": "2024-01-01T00:00:00Z",
  "dry_run": false,
  "action": "buy",
  "reason": "Scheduled DCA purchase",
  "rate_usdt_per_btc": 95000.00,
  "amount_usdt": 10.00,
  "amount_received_sat": 10526,
  "price_aware_applied": false,
  "order_id": "uuid",
  "status": "completed"
}

action values: "buy" | "skipped" | "failed" | "disabled"

DCA Philosophy

• Consistency: Run on schedule regardless of price (unless price_aware is on).
• Fixed size: Same USDT amount each cycle — buys more sats when price is low.
• No timing: DCA removes the need to predict market direction.
• Long-term: Works best over many cycles (weeks / months).

Safety Rules

1. Never DCA if node has insufficient USDT.
2. Never DCA if BTC balance < stop_loss_btc_sats (node is in distress).
3. Cap at amount_usdt × 3 even if price-aware doubles the amount.
4. In dry_run: true: simulate and report, never execute.
5. Log every run — both buys and skips — for auditability.
