Don ratio

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

Notes de version:

add max and low point of the donchian channel ratio
This are the poits where the channel at max low or high , after we expect change of trend
there is no alerts for this but one can make it in the code

Notes de version:

fix some issue with the high and Low
