Normally and if you are not on the same candle that the trade was opened, you will not have any issue.

Sometimes on the same candle an EA may re-open the trade, but only if its coded that way.

Some EAs may re-open the trade if the trading criteria that opened it initially are still valid, so it all depends on the way the EA is coded.

 
And if it is poorly coded, it may continuously try to trail the stop loss of the closed order, with corresponding error messages, until you remove it from the chart. All depends on how it is coded.
