Senior help me 99% quality data for backtesting

Can anybody have 99% quality model backtest data of eurusd ?
Can anybody share backtest results of some scalper ea from mql market? . I need 99% backtest result

You use mt4 or mt5? At least with mt5 you can find your data here: C:\Users"user"\AppData\Roaming\MetaQuotes\Terminal"yourterminalcode"\bases"yourbroker"\history

Just delete the history files and your terminal will download fresh data from server.

I do this but my data quality is only 25%. I need 99% quality data. I am going to buy paid ea from mql5 website. I want to backtest some paid ea. can anybody help me

I’m sorry about that… Do you have mt4 or mt5? Because mt5 generally has more detailed history data and therefore gives more accurate backtest results. What broker do you have? I use Alpari and FXTM, both have 99% data from the last 10 years at least.
