Regular Trading Hours Levels
The levels Higher Low and Lower High may not be present on some days. The underlying price computation algorithm is changed to remove these levels on days when this level is not likely to be effective.
When these levels appears for a given day and price happen to meet the level, the likelihood of a reaction is now higher than before.
They are still not blind entry level. One must watch for demonstration of support or resistance before attempting a trade against these levels pair.
Demonstration may be a single five minute chart rejection candle. It does not need to display 15 minutes of support or resistance for example.
Here is a retro actively produced example for ES June 8 Friday 2018. This day only Lower High level is available for indices. Higher Low is not present.
