Is there any issue, which finds optimal parameters in a trading system?

I test "strategy analyzer" and I have excellent results, but then when it comes to live data it is a disaster.

Hello ElMagoR, thanks for your post.

There are a few reasons a backtest can be different from historical results. To start, please read through this post from our colleague Chelsea on the differences that can be seen and what to do to minimize the differences.

Citizens of the NinjaTrader Community, A common question we hear from clients is 'why are results from backtest different from real-time or from market replay?'. Live orders are filled on an exchange with a trading partner on an agreed upon price based on market dynamics. Backtest orders are not using these market dynamics.
