How to have an EA stop taking trades on some currency pairs and keep trading others?

[craftvfx]

I have and EA and it has been working great.  Recently I decided to add a few extra currency pairs for it to trade.  Turns out it's only ment to trade EUR/USD and USD/CHF and now its starting to make some bad trades.  I'm told I can't just manually stop the trades that are already opened,  it screws up the EA and the EA will try to competsat for it.  Now if I turn off "auto trade" button at the top, this will prevent any more trades to be place, but it will also not make any new trades on the pairs I want it to be trading. I want to have the two currency pairs EUR\USD and USD|CHF continue to trade but turn off the others from autotrading any more and to have it eventually close those open trades.  Is there a way to do this?  Would turning off the option in the Expert advisor,  "Allow live trading"  keep those charts from placing more trades?  Would the already open trades close on their own still by checking this option?  Thanks

Yes, but the EA will stop managing the open trades from stopped pairs.

Where to check autotrading:

and

If you attached EA to the chart and you see "smiling face" so it is fine with autotading (in most of the cases):

If EA's face is not smiling and not happy so you can check everything once again:

It was for MT4 but MT5 is same with this case.

Example, -

• one trade is open for GBP/JPY by the EA,
• you turned "Allow live trading" off on the EA attached to GBP/JPY chart,
• and because of that - no new trades will be opened for GBP/JPY, and
• EA will stop managing already opened trade for GBP/JPY so you shoul close the trades manually by yourself, or wait when the trade will be closed by itself by stop loss or take profit.

An EA trades either on the instruments that you attach it onto or on the instruments that you choose from its settings.

So in your case you either have to attach your EA on the right charts (of the pairs you want to trade) or you set it to trade the desired instuments only within its settings (if it had such option).

The already open trades only close if the levels (TP&SL) are set otherwise you will manually have to close them at some point , which should not form any problem.

Also you have to be specific upon designing a EA code it or tell the coder that it will only be allowed to trade instruments that are in market watch.

So you can add and remove instruments from and to market watch for the EA to trade.

The code should be written well in order to support this.

No EA can function on a dead/closed laptop, unless you had migrated your EA on a VPS and still opens trade there.

If you are using MQL5 VPS, login into your MQL5 account on your new laptop and synchronize/migrate with your MQL5 VPS on an empty chart, to stop the EA from trading.
