Turn an Indicator into a "Number"

Greetings ...

I've got an active EA that "works fine" but ... the logic is not quite correct.

The next thought is to tie the Trailing Stop Loss to an Indicator's value. My challenge is converting the indicator to a value that the EA can recognize.

So, I'm seeking a "section of code" that will allow the EA to operate with a TSL reading the ATR (Avg True Range) as follows: TSL = ATR+X where X = addt'l pips.

I'm reasonably good at "cut and paste" but the technical aspects of coding still escape me. Would appreciate if a "cut and paste" solution could be provided.

Thanks to all ...

Everyone's good at cutting and pasting...

but to come up with a cut and past section of code requires a whole lot of assumption on the code context for the EA that is to eventually use it.

If you want proper help, you should post the code of your EA.

What the heck... indeed.

Yes, I guess I can understand the frustration that would occur. I'm trying to simplify this for you (and others) but it's probably like a doctor trying to help a patient without really knowing what hurts.

Doctor - "Here's a bandaid for your nose"
Patient - "But doc, I think my arm's broken" ...

I'm happy to try to work through this over the weekend ... but don't be surprised if you see the code posted with appropriate comments about my pending confusion.

My thanks for your help.

hey pip.... if you have active EA that "works fine" maybe we should be asking you questions....

don't let trailing stop get you stressed out, save that for something real hard........h

Yo Hayseed ... nice to hear from you .

Yes, the ea does "work fine"... opens trades and closes them on command. Earning positive pippage is another story. The resulting slope on the P&L results graph has a very nice angle ... I'ld say at about "3:30" for those who remember non-digital watches. Makes for a nice and steady drain on the account.

Thanks for the shout out and kickin' in with your "cut & paste away". I appreciate 'em both.
