Hi mladen,
Could you please help me with this. I have tried some combinations and different things, but can't figure out how to do this. Thanks! 

Simon

The conditions should be more refined. For example : when both are signaling the same is very often. So, when exactly should they do that. On the first occurrence of that? On every occurrence of that? Also, if you are exiting on ever change of one of the two, the exits are going to be very frequent

Thanks for reply! Yes, this might not be a good strategy. It's just that if I get this as a template I can probably do some changes by myself later. What I want is the possibility to combine two indicators (and the use of their buffers).

Lets say the strategy instead should be: buy when both indicators indicate. And sell when both indicators indicate. It should happen after indicator change and closed bar. It should happen on every occurrence of that.

All the best!

Dear mladen,


I have an issue with the attached indicator:

when the indi is applied during the EA execution ( the standard moving average in MT4 ) the values are very different to the values wich are displayed applying the same indicator at the end of the EA execution.

Could you please explain why and if feasible correct the indi ?

Mr mladen ,

I am doing some change for the ma ribbon filled to ma channel but I have problem with the buffer .

Is that any way can hide the channel behind the histogram or make for the blank between the channel ?

I try to blank it but only can do it on one side , is that need to adding one more buffer ?

And one more problem is at line 44 , i cant extern or delete it .

it always have error come out .

Please give me some advise , thank you .

Steven .

YES , exactly what i want :D

But can you help me to check the code on line 44 'AlertOnClosedCandle' , why it cant delete or extern bool ?

This is my first time having this type of problem .

Any way i have learn some things on the buffer  .

Thank you .

Mladen just finished my customization in the previous indicator you modified. What's wrong in this code? It does not display nothing...No errors when compiled.

Correction :

Change lines 74 and 75 of sigma from this :

to this :

And it should work

Or remove the strict statement completely (since that indicator needs a complete rewrite if it is going to be used with the "strict")

Dear mladen,

I've tried both suggestions without succes  but I've realized that the indi does't update when running in a EA as in the following picture.

Should be possible to fix it ?:

Try it like this

Tried Mladen and it seems working but in the strategy tester it doesn't refresh itself and doesn't pop up the alert, when market will open i will try in real market. thanks
