I found a free ex4 expert that is shared on the web many years ago
it looks promising
it uses a fixed big stoploss (over 100 pips)
I would like to optimize this stoploss
but the problem is that it is not an extern variable so it doesn't appear in the expert inputs when attaching the expert to a chart
how can this stop loss be optimized or at least another stoploss be backtested by the tester?
can another expert advisor be built to take entry and exit in profit signals from the ex4 expert with different stop loss used ?
any third party software can help ?
any solution ?
