Looks like a buy to me

Price touched my first supply zone and price bounced off and to me when a supply or demand zone is touched once that zone is now invalid. Now price is coming back down into structure where I have my fresh demand zone around the 0.89000 area I'll be looking for buys in that zone. First target coming off at 0.89810, final target at 0.91000 and stops below structure on the 4h
