Market replay: Different chart on each play.

[lucyb]

When testing my strategies in Market replay sometimes I will see an order placed where there clearly wasn't a trigger visible on the chart.

I rewind the playhead a bit and when it plays again, the candles are slightly different. Are the candles different each play?

Also, I would like to ask. When testing market replay strategies, is the playback speed relevant in the success of the strategy getting triggers? I feel somehow playing it too fast I will miss entries.

I've also seen different order entries when playing at 500x vs 10x. I try to not play too fast because of it. I suspect at 500x Ninja is doing some kind of summarizing in the data processing, but it's only my suspicion so I could be wrong.

Hello lucyb,

Thank you for using NinjaTrader.


Playback with Market Replay data is very accurate, but note this pumps data out in 1 second intervals (which can cause small differences in when orders are filled).

Below is a link to a forum post that demonstrates how to find what is causing differences between real-time and playback:
