Inconsistent Backtest Results

[Gautam Heble-1756230857752]

I'm running into a consistency issue with my backtesting that's making it hard to trust the results.

I've been backtesting a weekly strategy, tracking all my parameters (index, backtest period, filters, market trend filter, etc.) in a spreadsheet along with results, screenshots, and CSV file export.

The problem is when I rerun the exact same backtest a few days or weeks later using identical parameters, I'm getting completely different results.

This is a problem because if backtest results re not reproducible, then I cannot rely on them.

For example, I tested a specific parameters set a couple of weeks ago and got the below results.

When I ran the same backtest parameters again today, I got a completely different result!
