OnEachTick vs OnBarClose Optimization

[thereyoflite1]

From: https://ninjatrader.com/support/help...ime_vs_bac.htm

"During backtest, strategies can ONLY be processed at the close of each bar."

I am doing my best to decrease optimization time. Strategy analyzer is done on historical data, so will having my strategy set to "Calculate.OnEachTick" cause longer optimization times? Or will the speed of Calculate.OnEachTick also match the speed of Calculate.OnBarClose in strategy analyzer because only OHLC data is available?

Hello thereyoflite1,

A backtest is always run OnBarClose so no matter what selection you have its going to be OnBarClose execution there. You can effectively simulate OnEachTick logic by using a secondary 1 tick series and programming the strategy accordingly but it will otherwise work OnBarClose for all series used. https://ninjatrader.com/support/help...ipt_strate.htm

If you absolutely need to test OnEachTick logic it would be suggested to avoid the historical based tools and use a tool like playback so you can move forward through time like you would normally in realtime.

Hello,

Thank you for your response. For the sensitivity of my testing, I'll probably end up using market replay to be most accurate.
