Sorry for such a basic question, but I have read the Amibroker manual, and searched pages and pages on Google and can't find the answer.
Basically, I want to change the parameters on the Bollinger Band to a 100 day moving average with the upper band set to 3 standard deviations and the lower band set at 1 standard deviation.
Below is the code for the standard Amibroker settings, what exactly do I need to change?
P = ParamField("Price field",-1);
Periods = Param("Periods", 15, 2, 300, 1 );
Width = Param("Width", 2, 0, 10, 0.05 );
Color = ParamColor("Color", colorCycle );
Style = ParamStyle("Style");
Plot( BBandTop( P, Periods, Width ), "BBTop" + _PARAM_VALUES(), Color, Style );
Plot( BBandBot( P, Periods, Width ), "BBBot" + _PARAM_VALUES(), Color, Style );
Thanks for any help,
