EA failed with "Every Tick" / minimum StopLoss value

 
Hello,

1. In MT4 tester, why most EA failed using model "Every Tick", even if they perform using the model "Control Points" ?

2. What is the minimum Stoploss value we can use in function Ordersend() ?

3. I think this minimum Stoploss value could be smaller (without getting Error 130: Invalid stops), testing a EA offline.
Did you experiment the same ?

Thanks.
 
the only way to use backtester is to every tick model. All other models are invalid.

MarketInfo(symbol,MODE_STOPLEVEL) gives minimum pips away to put s/l or t/p.

When offline, MT doesn't read marketinfo values from current broker so yes maybe you can get away with smaller stoplosses but they won't work in real life.
