Scalping tool for help finding potentially high probability reactive levels. I suggest using on a 5min chart.
GRAY BAND: yesterday's High-Low range
BLUE BAND: today's Developing Range. Mean of today's High-Low range so far and yesterday's High-Low range, this is calculated for each of today's bars
THIN BLUE LINE: the mean of today's range median and yesterday's range median.
Note: we do not use the DAILY bar via 'security()' to obtain today's high and low. This would essentially be forward looking, instead we use iteration to check from the current bar back to midnight, bar by bar. This then allows a developing range to be established as the day prints new highs and lows.
