AutoSupport(Source, LookBack, Threshold);
Source - This is the array that will be used for calculating the indicator. This can be the price or another indicator like RSI.
LookBack - Number of datapoints to use to calculate the support point.
Threshold - Percentage value that is used to determine if a price point is touching a support level.
The AutoSupport function computes a rolling support line for the data specified in Source. Because a source array is supplied to this function it is possible to compute this indicator on other indicators like RSI.
