The script pulls Lower Timeframe (30min) data to draw High/Low of Out-of-hours/AfterHours session (post-market session & next day pre-market session) on the Daily regular session chart. It then identifies significant AfterHours price changes and what happens to these price Spikes by the Open of the next day regular session.
You can change:
wether to show AfterHours High/Lows
wether to show AfterHours price Spikes
the AfterHours price Spike threshold (default = +/- 10%)
