We run a small MT5 stack with a 1 % daily loss cap. It had been in place for months and we trusted it. Replaying our own history, a day where every stop gaps at its instrument’s 99th percentile reaches 13.84 % of equity . Not 1 %. The cause is simple once you see it: the limit counts the stop, not

I do most of my development runs on M1 OHLC because it's fast. Before I release anything I rerun the finished EA on real ticks. On EAs that wait for a setup and give the trade room, the two modes usually land close together. On anything with a tight target they can be far apart. In 1 minute OHLC

A pattern I see in many EAs: read SymbolInfoSessionTrade for today, take from % 86400 and to % 86400, and compare them with the current time of day. It breaks when a session crosses midnight. The returned 'to' can be later than 24:00 (a session from 21:00 to 08:00 the next day), so to % 86400

Hi all, In early October 2026, I went through the product pages and public signal track records of ten of the best-selling scalping and martingale-type EAs on the MQL5 Market, and checked every figure twice. I'm not naming any sellers — patterns matter more than people. Here is what kept repeating

After a lot of bought EAs, prop challenges and backtests that looked great, I ended up with a short checklist I now go through before I pay for anything. Backtests weren't the problem. They just never told the whole story. Here's my list. Curious what you'd add or disagree with. 1. Deposits dressed
