Tested with multiple Inverse pairs.
Blue Arrow = Buy
Red Arrow = Sell
Access to the script is available for a one-time fee of $5. I would suggest studying the strategy tester (with Heikin Ashi Candles turned on) before deciding to buy the script. Send an email to firstname.lastname@example.org to initiate the transaction. I personally unlock it for each person individually.
Caution: In rare cases, the arrows might repaint. It is recommended to check the indicator 15 minutes prior to AfterHours begins, to make sure the arrow is still present. If so, it is likely that it will remain for the rest of the day.
STRATEGY TESTING THE SCRIPT
Keep In Mind that TradingView strategies execute 1 bar after the signals are confirmed, so the gains would presumably be better than what the strategy tester presents, since the arrows are produced one day before the strategy executes buy/sell orders.
