Pbs with strength out of a bottom formula/indicator

Hello,
I have a problem with the following formula/indicator :
VOLUME>=Ref(VOLUME,-1)*1.5 AND Stoch(20,5)> Stoch(20,3) AND CLOSE<= O+(O * .3)OR CLOSE >= Ref(CLOSE, -1) - (.3 * Ref(CLOSE,-1) AND CLOSE <= O + (O * .3) OR CLOSE > Ref(CLOSE,-1) - (.3 * Ref(CLOSE,-1)))
It is supposed to detect strength out of a bottom. Apparently there is no syntax error in it and it provides a signal.
But the way it is written (lack of parenthesis to delineate clearly items for precedence) make me quite unsure about what is calculated.
I am particularly worried and uncomfortable by the part I highlighted in bold.
Your help will be welcomed.
Thanks and best regards

if you just had AND linking your conditions, the formula would be fine. However, anytime you mix AND and OR links, you should put parenthesis around the section the OR refers. consider:
A and B or C and D
did the author mean:
(A and B) or (C and D)
or:
A and (B or C) and D
or something else. I can easily show at least two other ways to combine those four conditions.
