24 Hour Advance – Decline index and Momentum numbers.
These momentum calculations are derived from the McClellan Summation and McClellan Oscillator ( which are both generally free indicators on most platforms ).
The indicator displays higher time frame Momentum numbers and is able to retain the data describing the development of the higher time frame calculation.
The while line is a higher time frame (30 min) momentum calculation with development data retained. The lighter red line is the same calculation where the development data is lost (that’s standard). Seeing development often gives very useful information during intraday trading and especially scalping.
