Negative offset

[Hank M]

As discussed in strategy class on weekend, I want to write a negative offset (like a lower Bollinger band but exponential moving average). I wrote this successfully for the upper average as Close[0]==[EMA(10][0]*[1+.75] but for the lower it must be same but the +.75 becomes -.75. I can’t get this to work in the NT strategy editor as it always starts with a positive value. I would appreciate any ideas on the best way to do this.

Have you tried entering into the "Offset" parameter

-0.75

?

If you're going to use this in a strategy, I'd recommend encapsulating that logic in an indicator so you can easily put it on a chart.

I don't quite understand the logic you are going for. What is the .75 supposed to be exactly?

[Hank M]

Yes, but it comes out +-.75, and does not plot.

[NinjaTrader_Ray]

Right, that is correct.

- What are you expecting to plot? If you are using a BollingerBand and you have "Plot on chart" enabled, it will plot the BollingerBand indicator itself.

[Hank M]

In Metastock code I can plot this as "
C>(Mov(C,10,E)+(.75*(Std(C,8))" The reason I do not use the NT Bollinger is that it only plots as a simple MA and is not adjustable to EMA or whatever. The longside of this plots well using the offest tool as in my orginal post. However, it always defaults to the long side, and does not anticipate a negative offest which is the equivalent of a band below the market.

So we are on the same page -

When you say "plotting" you are referring to the EMA on the right side of the condition builder, correct?

If yes, its plotting the EMA(10) *without* the offset. Offsets are not used to determine plotting but just used to create the condition.

[Hank M]

It plotted on my chart correctly when I ticked the plot on chart box.

I can assure you that it will *only* plot the EMA(10) and not EMA(10) with an offset.
