More than 100 subsequent user events

Ok. I have a small issue where by when I run my strategy using the associated indicator, I get the below error.
Sometimes the strategy would be working fine for hours then it throws that error. Other times I cannot get it start due to it throwing that error. I have to wait a few more bars sometimes then it starts, but crashes later on. If I do market replay, it doesn't crash, I can play 3 months of Market replay one time and it doesn't crash, but go live and there it is. Sporadic. Even when the indicator loads to the chart, if I reload the ninjascript I get the error also.

Please let me know how I can avoid this. Thanks.

I am using the indicator DeltaMomentum that is available on the NInjatrader ecosystem.

Hello, thanks for your post.

In the source code for DeltaMomentum, there is an extra override of OnMarketData and OnMarketDepth, please remove those from the source code first and test if this problem happens again.

Remove:

protected override void OnMarketData(MarketDataEventArgs marketDataUpdate)
{

}

protected override void OnMarketDepth(MarketDepthEventArgs marketDepthUpdate)
{

}

I look forward to hearing of your results.

Ok. Looks like it is holding. Will continue to monitor over the next few days.
