History Quality

How do I get the best History Quality in backtests?

You select 'Every tick based on real ticks' modelling in your Strategy Tester Settings tab.

This downloads history ticks directly from your broker's server.

Yes, I know. I did that.

But i get only 33%.

Try with a different broker account type, if this is a demo account, try logging into a real account and try again.

I achieve 99-100% backtest results with a real trading account.

Also the backtest quality depends on the testing period, most retail brokers have real tick historical data for the last 2-3 years only.

It depends on the symbol.

For a specific symbol on the same broker, I read in the Strategy Tester Journal log:

Tester ****: history data begins from 2024.03.19 00:00

Tester ****: ticks data begins from 2026.01.02 00:00
