Where i get the best highest quality datas for backtesting in forex and stock

Dear together,

i need your opinion.

Please tell me a very good and trustful source were i get the best highest quality datas for backtesting in forex and stockmarket and for strategyquant, for creating strategies?

Hello,

this service offers tick data across all possible markets https://www.tickdata.com

What backtesting engine do you intend to use in SQ?

Hi,

sorry for the late response. MT 4 should be the backtest engine. Is there something to note if I order there data’s?

tomas262? Any opinion?

https://www.tickdata.com looks fine.

But I can´t find a price. Have somone information about the coasts?

I think it is not so cheap?

Hello,

not sure about quality of their data. You need to search for some reviews about them. I refered to them because it is what google offered me among first few search results 🙂

I use tickdatasuite, it is tick data from Dukascopy, great tool because it works on mt4 and gives 99% backtests

That is the same source as in StrategyQuant 😉

I don’t understand why this subject seems to get so little attention.

Especially the tick datas (or minute datas) are the basis of all expert advisor!

if they are of poor quality, the expert advisor is no longer usable.

Do all of you only use data from dukascopy or do you just not want to share your “know-how”?

Maybe everyone is so busy with the test of SQ X that nobody has time for the topic? But even there, data quality is the most important thing!

Hello,

you are right that the quality of data is critical. But it also depends of type of operations you want to perform. For robust strategies trading strictly on bar close on higher timeframes it does not really matter what data source you use as long as you keep timezone setting correct. Such strategies should perform good across all CFD/FX brokers. On the other hand if you focus on fast trading for small profits traded on a smaller timeframe (like M5) you should definitely  stick to your broker’s data especially if your broker is non-ECN/STP

For futures/stock traders the situation is easier. Trading is centralized on exchanges so data providers should theoretically have the very same data (volume, depth, OHLC)

Thanks for the feedback.
in principle, however, the data quality should ALWAYS be the best so that one can always assume an optimal result.

For this reason, I find it difficult to understand why the general interest on this subject seems to be so low…..
