CalculationMode.Dollar?

[whitmark]

I would like to suggest that a CalculationMode.Dollar be developed for the SetStopLoss(), SetTrailStop(), and SetProfitTarget() built-in functions for use in the the fully disclosured overide signiture. In my attempt to get CalculationMode.Ticks to work as a substitute by using:

StopLossTicks = StopLossDollar / (Instrument.MasterInstrument.PointValue * Ticksize);
SetStopLoss("BuyEntry", CalculationMode.Ticks, StopLossTicks, false);

I would get an error when I execute this in the Initialize() method but not in the OnBarUpdate() method. I realize other override signitures can accommodate Dollar amounts as a value, but then I loose the ability to address a specific fromEntrySignal reference. Is this currently a limitation or am I overlooking something? Any thoughts on workarounds would be appreciated. Thanks!

Not sure I follow. Doesn't signature below (and related) do what you are looking for?

protected void SetStopLoss(double currency)

True, but let's say I want to use different dollar based stop loss amounts for "BuyEntry" vs "SellEntry" entry signals . . . how would I go about doing that for both the call in the Initialize() method and subsequent dynamic modifications in OnBarUpdate()? Thanks.

Call it twice passing in the different entry signal names with the different stop values. Same in OnBarUpdate().

Please allow me to clarify. If I use the following signiture, I can do dollar values but I can't reference a specific fromEntrySignal . . .

SetStopLoss(double currency)

and if I try to convert it to CalculationMode.Ticks with the following code, it appears that the call to the Instrument object fails in the Initialize() method. Any particular reason for this?

BuyStopLossTicks = 150 / (Instrument.MasterInstrument.PointValue * Ticksize);
SetStopLoss("BuyEntry", CalculationMode.Ticks, BuyStopLossTicks, false);

SellStopLossTicks = 250 / (Instrument.MasterInstrument.PointValue * Ticksize);
SetStopLoss("SellEntry", CalculationMode.Ticks, SellStopLossTicks, false);

As you suggest Ray, I could just set a first run switch in OnBarUpdate() and call this code there if there is no need for an initial reference in the Initialize() method.

Hence my suggestion for a CalculationMode.Dollar and a signiture profile that can be used in the Initialze() method and includes a reference to a specific fromEntrySignal to enable differential long vs short dollar based stops.

Thanks,

Instrument may be null in Initialize() therefore we prevent calling it.
