I am optimizing an ea TimeFrame H1 with every tick
(using my own tick data & real spreads) ; it is a high-low based scalper
with relatively tight stops/profits.
After it is finished, when I go to "optimization
results" tab and double click on a specific line to run a backtest on that
specific set of optimized parameters, I sometimes get quite different backtest
results (number of trades, pnl...) than the results shown in the
"optimization results" tab.
Any idea why?
Not sure I understand. Do you mean that in Optimization MT4 will use a fixed spread vs a variable in backtest ? ( my .fxt file are built with variable spread : I use an ea to gather ticks with broker in csv format, then I use CSV2FXT to get the correct .fxt files with variable spread; backtest & optim are run on this )
