Hi Mladen/Mr.tools.
I tested this attached indicator and gets good results by trade manually with a slight changes for take trade.  If possible the arrow painting poistion and logic can modify, this will be nice..
here the changes..   and attached snap

1. The Main bar body cross the channel bottom/top line at close price (bar 2)
2. if the next bar (bar 1) trend is reversal and the close price value is LOWER than bar 2 close price - DOWN
3. if the next bar (bar 1) trend is reversal and the close price value is HIGHER than bar 2 close price - UP
