How do you do a simple program with IF statements in MQL4 such as

If price=level 2 then sell.
if price= level 3 then sell
If price= level 1 or level 4, close all trades
restrict trades to 1 per level

with levels set by an indicator or manually


Sorry if this is an impertinent question but it would be good to cut to the chase and avoid learning all the colours, variables, graphics etc etc- just to be able to try out some simple ideas


an example program for the above would be fantastic

thanks
