Order execution within MT4

 

I have just been introduced to MT4 and have a question on using the "Expert Advisors" in auto trading mode.

Are orders generated by an indicator within the Expert Advisor executed intra-bar or upon completion of the current bar?

Also, if you have parameters to take profit at certain levels and move stops accordingly (i.e. sell 1/3 at +10, sell 1/3 at +25, then trail by 25), are these take profit orders executed intra-bar?

Thanks,

Steve
