basic strategy short prior support long prior resistance

if prices goes up and touches a prior support (most of the time from prior day) then its time to short

so either use the swing indicator or draw your self the 30 min swing points

if you missed the 18500 short today, monday will most like have a rally up to this level

but in order to with max amount long there needs to be now first a new high and then a price to go back to this new high point to have a solid support level for the next uptrend...
