How to backest trading strategy for longer duration like 1 year or 2 years

PI limits backtesting to last 120 days. However to check a positional trading strategy its not long enough. How can I backtest for much longer duration like 2 years on nifty hourly charts.

We will soon start providing much larger data to backtest. But make sure while doing that, you don’t open the backtest chart, and also use a powerful machine.

Even the maximum limit to add scrips in the market watch and the number of charts to be opened at once is annoying. Please resolve this issue.

Thanks Nithin it will be great if you could come with this. Actually in previous version of PI this limit of 120 days was not present so i could backtest till last 5-6 months data, but the latest version has imposed it. But anyways I will wait for the much larger data set…
