Choppy Market Replay

[JesseOffshore]

Hello,

New to ninja trader and trying to get familiar with the software.

One of the main reasons I decided to try Ninjatrader was the market replay feature. I wanted to be able to fast forward and rewind etc.

My problem is that I can not seem to get the market replay to playback like it does in real time. It seems choppy and only updates every second or so. Its not smooth its almost impossible to use. At one moment im looking to enter a trade, the BOOM it jumps ahead and I lose my entry.

I was hoping that it was going to playback just like it does in real time. If it doesn't playback naturally then its basically useless.

Is there some settings I can adjust for performance? Ive searched high and low on the internet but nothing has solved the issue.

Hi JesseOffshore,

Since I use Market Replay a great deal for developing my coded strategies, allow me to ask the simple question: Verify that your playback speed is at 1x. That should provide you will real-time playback, as I understand it.

Somethings to consider, depending on the instrument and the time of day your playing back, the market can naturally be very choppy. For instance, ES or MES in the opening minutes of Regular Trading Hours or during news announcements is typically quite choppy.

Here's an excellent resource to look at historical news events to see if you're trading during a impactful news event.

Use the monthly calendar in the upper left to find the day of interest.

Hope that helps!

Thanks for the reply.

Yes ive got the speed at 1x. Ive tried all the speeds. For whatever reason no matter what I do its always choppy and jumping around. The playback on 1x speed is running at the right "time" but the candles form in jumps, if that makes sense.

Hi JesseOffshore,

I figured as such but just wanted to ask to cover the bases. It does make sense what you're saying. I think the market has taken on a new persona of late, if you will. It has become quite choppy at times when outside RTH and news events.

Hopefully, NT Support will provide some insights.

Kind regards,
Matt

Was there ever any follow up to this issue? I find playback to be choppy and jittery as well almost as if bars are updating ever second instead of by every tick like while in the live market.

That is EXACTLY how market replay works. The UI is updated once per second. The UI (including charts, SuperDOM, etc.) is not updated every tick.

IF you have a decent PC, you can try TickRefresh. It doesnt work well on my chart setup, but if you use time charts it may help. Outside of that, nothing that Im aware of can be done. Its a frustrating thing.

Tick refresh works VERY well on live markets though, but can really bog down a sub-standard PC so play with it first and test it out. Ninjatrader does not update every tick even in a live market. Its every 250ms, with this you can set it to 0ms (every tick).
