Indicator issue with BuySellTick

[WHICKED]

There was a indicator that was provided via the NT support staff for buy/sell tick data usage here: https://ninjatrader.com/support/foru...dwhileinactive

The issue that is being seen is that if you setup Tick Replay on the chart and set the chart to Bars and bars to load it has an issue with the Update method:

The actual error is as follows:

2022-03-03 22:40:45:566|3|4|Indicator 'BuySellVolumeOneTick': Error on calling 'Update' method on bar 1032: Object reference not set to an instance of an object.
2022-03-03 23:05:29:092|3|4|Indicator 'BuySellVolumeOneTick': Error on calling 'Update' method on bar 1000: Object reference not set to an instance of an object.
2022-03-03 23:05:41:238|3|4|Indicator 'BuySellVolumeOneTick': Error on calling 'Update' method on bar 1000: Object reference not set to an instance of an object.

Pressing F5 will sometimes cause it to do the similar erroring - eventually it will process but it will randomly fail and give a similar error as above.

Hello WHICKED,

Bars To Load will affect all added data series, so you will need to have BarsToLoad reflect a high enough value where there will be enough ticks to form a primary bar.

I updated the example in Brandon's post and tested 1000 Bars To Load with Tick Replay on a ES 03-22 1 minute chart with Tick Replay, and did not get an error.

Also, you shouldn't be using this sort of indicator on a Tick Replay chart. The purpose of using the OneTick approach is so you do not have to use Tick Replay on the chart. Regardless, I am not seeing errors when I test Tick Replay with the updated example.

What do you mean by this statement?

Hello WHICKED,

When I test the updated script with Tick Replay, I do not get an error.

I get formed historical bars for just the 1000 bars of tick data that was loaded with the indicator. (Screenshot attached.)

So even though it would not be advised to use an indicator like this with Tick Replay, or with BarsToLoad, I am not getting any errors.

Please re-download the script from Brandon's link if you do not get the same results.

Hello WHICKED,

I am referring to the "BuySellVolumeOneTick" example you brought up in this thread.

I updated the example in Brandon's post

Post here.

I do not get errors with Bars To Load and Tick Replay with the updated example. (Please re-download the "BuySellVolumeOneTickExample.zip" file and import to get the updated version.)
