Supply & Demand zone based on EMA Cross

[xpsal]

Hi there, anyone please help create a study as following. example drawings attached.
1. use the top or bottom of the candle where EMA9 and EMA21 crosses as the top or bottom of the supply or demand zone.
2. use the previous previous higher or lower before the cross as the other part of the zone.

• if EMA9 Crosses below EMA21, then use current candle and the last higher candle's high to generate supply zone
• if EMA9 Crosses above EMA21, then use current candle and the last lower candle's bottom to generate demand zone

2. supply zones use color red, and demand zone uses color blue.(or any color suits)
3. only show 2 sets of supply and demand zones.

i started on this.... thinking the rules were listed well...
then i realized they aren't , so i stopped for now.

it is very confusing to combine 2 sets of rules ( buy and sell) into 1 set. don't do that.
rewrite the rules into 2 clear sets of rules

--------------------------------

rule1 , top or bottom of what ? the wicks? body? don't be vague. this rule is confusing.
should say , if EMA9 crosses above EMA21 , then do stuff

rule2 , higher what? lower what?

you have 2 rule 2's
2nd rule 2 , you say red, but show a tan cloud
