OrderFlowCumulativeDelta Indicator

[NinjaTrader_ChelseaB]

Hello ij001,

Values[1], Values[2], and Values[3] do not exist. These are invalid indexes.

You would need to call AddPlot() 3 more times for these plot series to exist.

Hello ij001,

Candle body outline	OutlineStroke.Brush
Candle wick	WickStroke.Brush
Color for down bars	DownBrush
Color for up bars	UpBrush

Print(OrderFlowCumulativeDelta(BarsArray[0], CumulativeDeltaType.BidAsk, CumulativeDeltaPeriod.Session, 0).DownBrush.ToString());

Hi Chelsea,

I have been working on it. First I am trying to get the indicator to display the delta candles before I work on the mirror aspect.

I seem to get hung up with the "index out of bound error"

That is: Indicator 'OFCFDeltaCandles': Error on calling 'OnBarUpdate' method on bar 2: Index was outside the bounds of the array.

I've read the NT guide on CurrentBar but still get the error. What am I missing?

Hello ij001,

Candle body outline	OutlineStroke.Brush
Candle wick	WickStroke.Brush
Color for down bars	DownBrush
Color for up bars	UpBrush

Print(OrderFlowCumulativeDelta(BarsArray[0], CumulativeDeltaType.BidAsk, CumulativeDeltaPeriod.Session, 0).DownBrush.ToString());

Hello Irvin,

The Order Flow Cumulative Delta does produce DeltaOpen, DeltaHigh, DeltaLow, and DeltaClose values, and these values can be called from another indicator.

https://ninjatrader.com/support/helpGuides/nt8/order_flow_cumulative_delta2.htm

Theoretically it would be possible to do something similar to the mirror bars and multiply the value by -1 and then plot the values in the new script.

Hi Chelsea_B,

I am able to plot the various values (DeltaOpen, DeltaHigh, DeltaLow, DeltaClose)

Any insight on where I can get code for the "Parameters" below?

Candle body outline	Color and line settings for the candle body outline
Candle wick	Color and line settings for the candle wick
Color for down bars	Color for bars that have a close less than the open
Color for up bars	Color for bars that have an open greater than the open

Hi NT,

I have a lifetime license for NT.

Occasionally, I use Mirror Charts for visual purposes.

I'm wondering if there's also a way to also mirror the OFCD (OrderFlowCumulativeDelta) indicator using some code in a new indicator.

What would you suggest?

Thanks in advance.
Irvin
