MT5 Backest Quality

Fernando Carreiro  
iberhack: Hi, at first my mt5 backtest (with real ticks) had 99% 100% quality (when backtesting last 3 months). And if i backtest a year the quality decreases to 60%... How do i download more tick data for better quality backtest for multiple years back?

Your broker probably does not have tick data that far back.

You can find out, by opening the Symbols (Ctrl-U), selecting the symbol you want and then selecting the "Ticks" tab. Then set the time range you want and hit "Request". It will then download the data and you can see from the first tick how far back it went.
