Enter extern Variables into a alert window if missed.

Is it possible?

I'm writing an EA that works in groups across several pairs, but will need to have several different instances running at the same time. I was planning on using a couple extern variables to group the different pairs. It's a bit rough as sometimes I will need more than one trade open on a pair, but in seperate groups,

ANYHOW, when you have a lot of ea's attached to a lot of charts, it's a bit of a pain to make sure you enter the proper variables when attaching the EA. Especially during testing....(over and over again)

Its easy enough to code in alerts if you miss a data entry, but it would make things easier if you could just enter the values you want into an alert window as needed...is it possible? Any tips?

If you need to access variables across multiple EAs/Scripts, then let me point you at Global Variables. Hit the F3 key and you'll see the interface, read up on the functions to see how they work. If you're only reading the same values, it can stay pretty simple, if the EAs have to write to the same values then you have to be really careful.

If you haven't yet gotten started, I'd like to suggest you consider writing it as a single script which accesses data from multiple pairs and manages trades across multiple pairs.

Feel free to PM me if you have specific questions about this stuff.

thanks for the help!

My last attempt I figured globalvariables would be enough. I am doing my best to limit myself to 1 script however it will be extremely tough, so I basically am down to a "master" ea that controls profit level's/entry levels/exits etc. and a "slave" ea that basically just reads what the master has decided and follows suit in a couple lines of code.

I started off just letting the master toss out a globalvariable to send signals to the slave, but when you want to have multiple sets of pairs running the same scripts, a few identical master EA's tossing out the same global variable is an issue. I coudn't determine an easy way to make the globalvariable an extern variable that I can change as needed without going into the code...maybe I'm missing something there...

So an extern variable that sets the magic number for the set of pairs, and another that Identifies what pairs are in a set, seemed to be the way to go.
Each EA runs a simple loop to pull the information of it's "partner" pair out of the open orders on the account, using the magic number etc.

it's not a big deal, just a matter of convenience. I can just have an alert that I missed an entry and reset the ea on that pair. I also like to learn new things, so any idea's are of course welcome.
