      Hi Eros, thanks for your post.

      There are a few factors that can cause an optimization to either slow to a craw or just stop. The first one would be the amount of data you are backtesting. Another cause would be if the strategy runs on price change or on each tick with tick replay on, this can exponentially hurt performance. The third cause would be the code itself, something that would need to be optimized by the coder. Another cause would be the type of optimization you are running, performance is negatively correlated with the number of iterations/number of generations you are requesting.

      You should use Print statements to print out data from the strategy, this might uncover what is slowing down the system.

      If you backtest a small amount of data, does the same thing happen?

      I look forward to hearing of your results.
