Stop loss when market is closed

 
I've used the CTrader platform so far, and I am new to Metatrader, anyone knows how I could set up a take profit/stop loss for an open position when the market is closed ? it seems so obvious, why wouldn't it be possible ? 
 
If market is close you can not make any change.  
 

The market closed will con not do anything

need to wait for your broker will open and operate again

 
You already made whatever changes you needed on the last tick. Nothing has changed and wont until the next tick.
