Help with 'Close all orders'

I'm using the free Expert Advisor builder here http://sufx.core.t3-ism.net/ExpertAdvisorBuilder/.

I'm slowly getting my head around the actual coding of it all, but I can't figure out the code needed if I want to exist all open trades at once.

The existing code is this


And the opposite for Sell.

This however only closes one open Buy trade at a time. For instance, If I have multiple buy orders and want to close them ALL when the last daily candle closes below the 15sma, the EA will only close them one at a time for each daily close below the 15sma, not all on the first day.

So what would I need to do if i want all Buy orders to close at the same time with the same condition? (and tlikewise for sell)

Thanks.

You can find code snippets for close all here:

That thread is useful, but it seems it's "Close all" scripts are designed to work independently.

Just to be clear, I don't want an EA to close all orders, I want to tell my Current EA how to close multiple orders at once.

MelbTrader,

You might find the article How to write a close all script in MQL4 useful. I wrote it as a sort of tutorial for those looking to understand how the components fit together. The goal of the article is that at the end of it, you should be able to write your own routine / fit it to your specifications in your code.There are also a couple of finished close all scripts (the finished product) that may be downloaded for reference, one for all symbols, and one for the current symbol only on the site.
