Custom BarType Not Always working with Order Flow Cumulative Delta

[evanp90]

I created a custom bartype that pretty much works fine for everything e.g backetst, trading, charting. Sometimes, when the chart and strategy are left open from session close to session open I get the following error when adding the Order Flow Cumulative Delta indicator to the chart.

'Indicator 'Order Flow Cumulative Delta': Error on calling 'OnBarUpdate' method on bar 427760: Object reference not set to an instance of an object.'

Actually it seems like maybe that error is occurring on the secondary Tick series maybe based on the bar number. Any ideas why this may be happening?

Thanks,

Evan
