mismatched errors

[Lukasz Podkanski]

hi, can anybody give me advice on what historical data should i rely on?

i have developed simple EA and backtested it on my brokers historical data. Results were not that bad, but i was confused about data i used - M1 chart is only available for 1 month past so i presume M5 is used to calculate results.

Then I have downloaded historical M1 data from FXDD, backtest results were a lot better but there were 3 milion mismatched chart errors. Can anybody give an advice what to follow - brokers data (XTB) or downloaded from FXDD?

The best is download it from the broker that you are using. Because, different broker has different ask/bid value.

I use program Tickstory to get ticks from Ducascopy and generate tick history for testing with 99.9% quality. This way testing result will be much reliable than any standard tick generation techniques of MT4. You can google or youtube some tutorials how to use it.
