Programming the WilliamsR

[atrader101]

Hi

Using the function for WilliamsR always produces a significantly different result than displayed on the chart. For example, using AUDUSD from the forex.com feed, the last bar of last week (25/09/2009 17:00 EST) the chart value is -60.00
but the function returns -.36.73.

The code is:

double a = WilliamsR(this.Input, 21)[0];
double b = WilliamsR(21)[1];

Print(string.Format("{0}:Current: {1}, Previous: {2}", Time[0], a, b));

Thanks

Hello,

Why are you using this.Input? Use Input, Close, Open, etc. See if that makes and difference. If not please reply.

Hi Ben

I've already tried all those, as well as the overload with just the period; they all give the identical results.

Hello,

I'll have someone look at this on Monday.

For sure they will return different values because you are accessing different bars. [0] is the last bar. [1] is the previous bar.

Thanks Josh.

However value of the last bar of the chart and the value returned by the 0 bar are different. The function is returning values different than reported on the charts (for the same bar).

Thanks

You likely aren't comparing the same bars. Make sure you are using the same parameters and the same CalculateOnBarClose settings.

Thanks Josh. You must be right because it's ok now.

Sorry for wasting your time.
