i am quite nude in this field. i'm trying to program the following EA with great difficulty: can anyone help direct me.

on H1 timeframe, if MA13 (moving average set to 13) goes above (crosses) MA120
and
stochastic 120 > 50 and
sto 15 > 60

then buy

if MA 13 goes below MA120 and
sto 120 >50
and sto 15 <20
then sell

with the parameters changeable
