Trades not copying
The main decision-tree guide for enabled connections, account state, logs, symbol mapping, and sizing checks.
Symbols
Symbol not found or wrong symbol traded
Fix missing symbols, suffix or prefix mismatches, and auto-mapped symbols that land on the wrong instrument.
Sizing
Wrong lot size, invalid volume, or insufficient margin
Understand lot calculation, broker minimums, volume step rules, and margin rejections.
Stops and targets
SL or TP missing, rejected, or not copying
Handle invalid stops, blocked modify events, and the common case where the trade opens but SL or TP does not stick.
Exit behavior
Positions not closing or partial closes not copying
Fix close-event problems, partial-close mismatches, and receivers that stay open after the master exits.
Execution quality
Copying delayed, duplicates, requotes, or timeout errors
Work through duplicate events, latency, platform load, and fast-market execution problems.
Platform state
Market closed, no prices, or trade context busy
Fix MetaTrader and broker state problems that stop execution even when the connection itself is fine.
