Filtering bad ticks

[tommyjames]

Hello, Is there a way to filter bad ticks? I have the Real-time tick filter on in 6.5 but it doesn't seem to do anything.

Thanks

It will filter our "real-time" ticks only based on the % you specificy. There really is not much too see except you will not see bad ticks based on your % settings.

So if you don't have the chart up at the second the bad tick comes in, it will not filter it?

Here is an example (see attached). I have these spikes in most symbols I trade. Is there a way to filter them out?

Thanks

That is correct. We have historical tick editing on our list for the future. It is something we plan to address. Right now, you could export the data via Tools > Historical Data > Export, open the file, manually edit the bad tick, import the file back in again.

Hello,

Just a few seconds ago there was a bad tick in the IWM over $1. I had it in a chart at the time and was watching it real time. NT did not filter the real time bad tick out. Is there a way to fix this?

Thanks

- Please double check that "Real-time tick filter" is enabled
- If yes, what is the offset %
- What is the current trading price of IWM
- What was the price of the bad tick

For clarification, if NT saw (I think) three bad ticks, the first two are ignored and the 3rd will make it through since we then classify that is a good tick

[tommyjames]

Yes it is on, and it is set to 0.1, which looks like the lowest setting. The spike was about .80 , the IWM was trading about 75.10 at the time. So it looks like it should of filtered it.

For clarification.

- The data in the chart is real-time data and not retrieved from a historical source?
- If you right click in the chart and "Reload Historical.." are the bad ticks removed?

Real Time..........

after reload the ticks are still there

[NinjaTrader_Ray]

I would be curious if your data provider will clear these ticks out by tomorrow (try reload tomorrow) or if they will leave them in there.

What I suspect happened is that more than two ticks came it at those spike prices. If we see three successive ticks outside of the % offset you specifiy, we then treat the 3rd tick and subsequent ticks at that price as valid and do not filter them out.

[tommyjames]

So there is no way to filter bad ticks, I hear what you are saying but tomorrow doesn't help when I am trading today.

[NinjaTrader_Ray]

Sure there is. See post #4 for the workaround I provided.

That's not a work around for real time trading, by the time you do all that it is to late..............

If NT could open up the "3rd tick" as a variable users could control, then we could control the filter sensitivity levels for when tick considered good again in addition to the % threshold levels. Please consider this as feature request for NT7.
