Rationale & Trading Techniques
Delta – the difference in volume between trades transacted at the ask price and trades transacted at the bid price – is one of the key considerations in analysing order flow. Doing the formation of each price bar, Delta will rise and fall until the bar closes. The Delta Strength indicator provides an easy-to-read indicator showing the relative strength of the Delta at the close of the bar. An up bar with a closing positive Delta value of 200 when the maximum Delta value achieved in the bar was 1500 is a very different proposition to an up bar whose closing Delta Value was 1495 vs a maximum Delta value of 1500.
Delta Strength allows the trader to set a threshold percentage to show strong positive or negative Delta conditions. For example, only indicate when the bar’s closing Delta is greater than or equal to 90% of the maximum or minimum Delta experienced during the bar.
Note the three bars from 10:55:03 all exhibited a Delta Strength condition after rejection one tick below the Open that had been previously tested at 10:22:22:
