MQL5 프로필 열기One rule guides everything I publish: a trading product that cannot be backtested should not be sold. Every robot and tool I offer can be tested in the MetaTrader Strategy Tester, so you can check it yourself before you buy, on your own broker's data.
Just as important, the backtest has to match reality. My systems are tested on real ticks, with spread and costs included, then on years of data they never saw during development.
When live results drift away from the backtest, that is a warning, not a detail, and I treat it that way.
I believe every seller should follow this rule. Until they do, it is the standard I hold myself to.
