How can I plot a moving average based on the high or low, instead of the close?
Under Analysis Tools, instead of using the standard indicator like “Moving Average, Simple,” which is an average on the Close price only, use the “Moving Average, Simple OHLC.” When using this indicator, change the FidType under the Period setting. FidType 1 corresponds to an average of the Open prices. FidType 2 corresponds to an average of the High prices. FidType 3 corresponds to an average of the Low prices. FidType 4 corresponds to an average of the Close prices.
