Send me the spec, or your source if it's a fix. I'll check it and ask what's unclear, like the exact entry and exit rules, symbol and timeframe, or whether a signal fires on the current bar or after close. I'm quick, and often have a first demo ready the same day. You can test a demo-only .ex5 before you pay, and payment goes through MQL5 escrow.
I'll tell you what I tested and where: backtest, demo or live. I don't promise profit, just code that does what we agreed.
English works best. Russian and Ukrainian are fine too.
