How to use the NonLagMA V. 7 indicator for opening a trade in the opposite direction - MQL4 and MetaTrader 4

[Deleted] 2009.03.08 04:30 #171

Are you still coding EA's? If so I think this one would be easy and effective. The NonLagMa v.7 is an indicator that is similar to the Sanefx template. When the indicator changes color the EA would open a trade, as soon as the color changes it would close the position and immediatley open a trade in the opposite direction. Simple but effective!! Below is the mq4.

Thanks for taking a look!!!

Hi Jim

A fascinating indicator. I think I know just enough to make an EA from it ;}

I will keep you posted, thanks for sharing.

josef strauss 2009.03.08 12:09 #173

Hi would you please work on that attached EA to make it work. I can't figure out the variable to go the error away. Also maybe you can add another ma that if when crosses and the Heiken primary trade indicator changes it stays in. Like as filter. And maybe it also would work with Heiken with two separate heiken crosses to filter the trade. I noticed if Heiken with different settings work like ma and filter the trade.

That is awesome! I will be looking forward to it. I also have the manual for the indicator. If you send me a private email address I will send it to you. I think it would be very beneficial. I wish I could write these EA's.

Hi Guys,

I am a Computer Science student heading towards my masters, and very interested in Forex.

Basically, I offer to create a free Expert Advisor for whoever needs one. I just finished my own first Expert Advisor, it gave me a return of 100% over 2007-2008, but performs less good @ the years before 2007, some not even profitable. Therefor Im looking for more inspiration!

I am doing this for extra experience in both mq4 and forex trading systems themselves.

Oh and by the way, I am already working on the inside bar expert so do not come up with that one :D.

Send me a private message with your plan, and you can expect, if the EA is not too complicated, within one week.

Greetings!!

Hello. If you are still creating expert advisors please let me know.my strategy is very simple please email me at forexgls@yahoo.com thank you.
