Strategy and different Point Values in Forex

[daxtrading]

I am using my strategy on forex pairs and now this came up:

The Point Value for most pairs is 100.000 only the JPY pair has a Point Value of 1000
Other instruments like the Fdax use contract size.

Can I add a condition to change the Point Value automatically when my strategy is used on markets with different values?

daxtrading, you could unfortunately not change the point value used on the fly - you could though setup a different master instrument fresh and then use this to run your strategy on.

Forex has 4 decimal places but this code:

Instrument.MasterInstrument.Round2TickSize shows the price markers with 2 decimal places.
How do I get 4?

Can you please post a chart the indicator / code applied and the behavior you see? How's the instrument used then setup in the Instrument Manager?

Thanks,

I use a strategy plot like this:
Add(StrategyPlot(8));
StrategyPlot(8).PanelUI = 1;
StrategyPlot(8).Plots[0].Pen = new Pen (Color.DarkGreen,2);
StrategyPlot(8).Plots[0].PlotStyle = PlotStyle.Square;
StrategyPlot(8).Name = "BuyPrice |DarkGreen|";
StrategyPlot(8).AutoScale = true;

and

Instrument.MasterInstrument.Round2TickSize(BuyPric e);

if (.........)StrategyPlot(8).Value.Set(BuyPrice);

On which instrument do you run here? You can edit the plotted the indicator to override the default price markers used - http://www.ninjatrader.com/support/h...ricemarker.htm

This should help you out here.

It's not an indicator but a strategy and I use it on forex pairs.
Where do I put the code from your url?

Daxtrading, the default behavior is for plots to be displayed with only two decimal places. Bertrand's suggestion is for you to override this behavior so it shows the price markers with all four decimal places.

You should place the code on the same level as OnBarUpdate(), like this:

OnBarUpdate()
{
 // your on bar update stuff here
}

public override string FormatPriceMarker(double price)
{
    // Formats price values to 4 decimal places
    return price.ToString("N4");
}

}

I added the following just below the OnBarUpdate part, so not in it.
// FormatPriceMarker method of a custom indicator
public override string FormatPriceMarker(double BuyPrice)
{

// Formats price values to 4 decimal places
return BuyPrice.ToString("N4");
}

and removed Instrument.MasterInstrument.Round2TickSize(BuyPric e);

This is the error I get:

FormatPriceMarker(double) did not find methode to overwrite

daxtrading, I overlooked this earlier, but the FormatPriceMarker only works for indicators. It doesn't work in strategies.

Is your strategy calculating the precision to two decimals with Round2TickSize, or is it only plotting with the two decimals?

Please try sending the Round2TickSize output to Print() to see if it is calculating correctly.

Hi Austin,

When I print the Round2TickSize it prints four decimals.
It's the plotting with only two decimals.

[NinjaTrader_Austin]

Daxtrading, please put the FormatPriceMarker stuff in the StrategyPlot indicator and see if that works.

With great help from the NinjaTrader Team, I finally finished my strategy on Forex Pairs.

I learned so much from guys like Bertrand, Brett, Vincent, Austin and others.
Also this forum was very helpful.
