I'm looking for a Metastock formula that can cumulate an indicator I made every single day starting from 9.15 to 17.45 (these can be variables). To be clear, i.e. today, at 9.15 the first value is (the value of) the indicator itself, the 2nd value is the previous value of the indicator plus the indicator at that time, and so on up to 17.45.
The time interval (time frame) is 15 minutes.
