Effect of Disconnection on EA?

Experts please guide: What is the affect of disconnection on EA? For example, if I am running a EA that i programmed to buy at 1.8000 with a stop loss at 1.7950 and take profit at 1.8100. Suppose the EA is attached and after sometime i find that it is disconnected but the price is still away from being executed. Will the EA still execute the price at 1.8000 or will I have to remove the EA and attach it once again..
Also what if the buy price is triggered at 1.8000 and later I find that the EA was disconnected, but the price remained between 1.8010 and 1.8000. If I connect the EA at that time, will it works as previously instructed..Thanks for your help.

That is not an easy question to answer. A lot depends on how long the disconnect lasts and how the EA was written. Most disconnects that I experienced last less than a minute and the EA just keeps doing what it always does. I usually don't trade "stealthy", so I don't have to worry about SL and TP because the broker server will handle that. As for trade entries, most of mine occur on the opening of a new bar, so if one entry gets missed by some unfortunate event, there will be plenty more. Someone may have some anecdotal experience which the rest of us can benefit from, but my advice is to stay away from "stealthy" trade management in case there is a disconnect.

Thank You for your advice. Pardon my ignorance, but what do you mean by stealthy trade management.

Stealth trade management means that the broker doesn't see the SL and TP. This can be done by managing the trade inside the EA on the client and leaving the ticket blank. Supposedly this gives less information to the broker about the placement of SL and TP.
