Soon it will be easier to compare the results. I'm almost ready with the new data feed. It will provide DukasCopy data (same as TickStory) directly in FSB Pro and EA Studio. 

I'll provide first these symbols: AUDUSD, EURCHF, EURGBP, EURJPY, EURUSD, GBPUSD, NZDUSD, USDCAD, USDCHF,
    USDJPY, XAGUSD, XAUUSD, BTCUSD, ETHUSD, DE30, USA30

It will have a possibility to set the time zone and to customize the spread, swaps, and other params.
I expect to have a similar quality of strategies generated. We will see if will be necessary to continue importing own data or the provided data feed with the corresponding settings will be good enough.

Anyway, if we search for a perfect backtest match, we must use the broker's data.

If the backtest results are similar, use these that are easier to import. On the other cases, use the broker's data.

wow @popov thats a great news..it will be a big think.. so for now i update every week my tickstory data and it cost much time. also sometimes dukascopy data come with errors or a bad chart.

did you build it like you get every day the newest data...so we can everytime use these with the newest data,

@ratampla i have worked a lot with tickstory to get the best data..

. First you have to run their script on your broker to get the symbol informations like from your broker.
2. I export data...load the information file..set spread to 100 (10pips)
3. Export the file
4. When ready exported file open the mt4 with tickstory. And now you have to check if your chart looks good.
Often you download the data but get a very bad chart. It is mostly when you use more symbols at same time.
5. When you got it import to eastudio

So when it all done.. I have checked my Eas with 10 different Brokers and have 99% the same results. Also here you have to check if your broker have so much history data available!!! When not download manually Tools->HistoryCenter.

But there are brokers with only 1 Year of backtest data..
