ST Sir can we start the countdown in the above case if there is an intersection but setup continues beyond 9 bars.Thanks
That is exactly what he has written.
The variation followed here is to start Countdown on completion of 9 setup bars and intersection condition which can occur with bar 8/9 with 3 or more bars earlier.
Even if setup bar 8 is the actual bar that qualifies the intersection condition, you can begin CD1 on setup bar 9 provided the conditions are met.
setup bars can continue counting until an opposite flip occurs or the setup condition halts.
