Another thing I just answered my own question. Don't think lower step setting will be of benefit. lower the step setting the more trades it opens to mitigate the risk of the 1st position. slightly higher setting should in theory work much better. So, for example if the 1st trade is open. and it goes into drawdown around 20pips the next position will open. So, if the drawdown is 100pips it should in theory only open 5 trades every 20pips.
I have changed mine to 20. EA took a GBPUSD trade now. 1st position went into drawdown. 20pips later it opened another trade. Eventually it closed in profit. So it seems to be working.
Will keep everyone posted.
