evidently you can’t pick a reliable decent broker. do you pick them based on how many ads you see scattered all over the interweb, or based on their “bonus free money, double your deposit” schemes?
my broker (who i won’t name anymore, other than to say “D”) doesn’t restrict anything like that. market orders, limit orders, closing an order, merges, etc. the ONLY thing i could MAYBE see is that if you have a TP set, you MIGHT need to cancel it before closing the position. but i’m pretty sure my broker does an auto-cancel if i close the order (cuz it’s just a bloody obvious thing to do). then again, this is why i don’t pre-set a TP if i’m actually going to watch the market. it’s idiotic in my opinion to set a TP and limit yourself to only that much TP and no more (and indirectly refuse to take 5 pips less).
