Limitation of Strategy Builder in comparing prices

[smcllr]

How can I calculate the "Range" (High Minus Low) of the last 3 bars and then divide by 3 and compare that average to the last bar using strategy builder?

I can subtract all of the Lows from all of the Highs but without the benefit of parentheses, I can't divide by 3 or it will only divide the last number by 3.

Thanks

Hello Sam,

Thanks for your post.

The Strategy Builder is designed to build simple strategies. It is not robust enough to perform complex mathematical operations. The code will need to be unlocked to perform the calculation.

I would suggest to write your strategy as much as you can in the Strategy Builder, and then to make a copy that you can unlock and edit in the NinjaScript Editor. You can go to the Welcome page of the Strategy Builder, and then place your mouse over your strategy in the Strategy Selector and click Save As to make a copy. Once the copy is made, you can unlock the code and edit the code manually to add your mathematical calculations.

Something like the following could calculate the average range:

if (CurrentBar < 3)
    return;

double myAvg = ((High[0] - Low[0]) + (High[1] - Low[1]) + (High[2] - Low[2])) / 3;

The NinjaScript Editor tutorial gives a good transition from using the Strategy Builder to generate code, and using that generated code in an unlocked strategy.

We look forward to assisting.

Thanks Jim. I had a feeling.
