Using the ratio of donchian channel from early script we can calculate factor Z which is the estimate of the high ratio and the low ratio
crossing it with +100 and -100 we can produce the signals with addition on non repaint donchian ratio channel
inside the script one can take profit for both long and short , buy again and sell again with stop loss if needed
by the same logic we can calculate factor to z to any channel we want once we create the correct ratio to it
