Help with make CT indicator for MT4

Hi guys

I have one idea for Counter Trend indicator for MT4. But I don't know how to code it.

Is here someone who can help me with programing this indicator?

ea

I can possibly do this for you, there may be a few conflictions but have done something similar few months back.

Ea

Be careful with counter trends they can really confuse trades if not done properly.

Hi Expert EA

I know but I have one deadly good CT system but it is hard to watch all pairs therefore I am looking for help to do indicator it will be much much better.

my overall result of the CT are about 80% winrate!!!

Ea

What lot sizes do you trade, how many trades a week, what pair?

I trade Live micro and on demo mini

I am trading overall 11 pairs and this is the problem I can't catch all CT because it is too much but when I see some I take it only one bad think about CT is RR it is only 1:1 max 1:1.5 but the winrate is big like I say previous.

and how many trades per week? sometimes one sometimes four-six. When I see CT I take it but I want code some indicator for help me to be more accurate
