Either I’m stupid or I go nuts. For practicing MQ4 programming I’d like to code an indicator which is based on a usual Donchian Channel (DC):
However, the channel is separated into two channels, a bull channel as well as a bear channel. The bull channel only repaints its position if the upper DC band goes up, the bear channel only if the lower DC band goes down:
But I have serious problems to transfer the right value for the bull channel if the upper DC goes down and vice versa. Maybe one of you could post a little code example how to solve it. I assume I have to use an if loop, do I?
Hi @Anti,
I’m really not sure whether I got that right. You’re talking about two channels. Do you mean the upper and lower border of one channel or really two channels?
A little terminology issue: if is a conditional operator, and usually it is not used to create loops first of all. You can do so, but mostly it does not make sense. MQL standard loop operators are for and while.
If you post your sample I’ll have a look at it. I think for the purpose of practicing this is better than just downloading a working indicator. If you want to go that way you can find thousands of them by just asking Mr. or Mrs. Google.

Hi @simplex,
I’m really talking about two indicators. It is what I concluded from both pictures posted @ FF.
I can’t show any code as this is the core question of the whole code. But ok, I’ll ask Mr/Mrs Google. Nevertheless, thank you.
… And here is the proof that I go nuts … I meant for loop …
Ok,
It’s just that the pics are so tiny I hardly can identify the details.
Good luck!

Sorry. Either right click on it -> open in new tab or use that links for the usual DC and the “advanced” version.
