Its not possible to take profit when stop loss function is activated because it's assumed that you are already making loss from the trade that's why you used stop loss in the first place.
It's a case of wanting to eat your cake and have it.

No it is not. You can put stop-loss (or take profit) even before you have anything (limit order). It's just about conditioning:

condition 1: enter position if price reaches X
condition 2: if position entered, exit position if price reaches Y (Y<X) OR if position entered, exit position if price reaches Z (Z>X).

It's actually quite simple and I don't understand why exchanges don't have that option. Because mostly they don't.

If that can't, it's better to trade with two different accounts where the first account is to make a stop loss and the second account to take profit. And in my opinion this method is the same, though a little ineffective

I believe that it's simply because their costumers are not asking for it in a big enough number that the management board actually see it as a priority and implements it. It would need to stop their operations for some time and increase their expenses when implementing and then debugging if it fails since it's a new implementation. In the case of Exchanges that are already functioning of course.

Some want to offer the best service they can and constantly seek for improvements to implement but sadly not everybody thinks like that, it would be interesting. The simple fact of having conversations about it in the forum could create more awareness about it between decision-makers in Exchanges.

literally you cannot use take profit and stop loss action at the same time
but practically stop loss does not mean your closing a trade with automatic lost , sometimes the altcoin you chose pumped but then you doesnt want to set a sell order yet  but then you are anxious that it might dump you can set your SL in a price where you still have a gain.
sorry but this is how i understand the scenario. Sounds greedy yah  

When we use stop loss it doesn't mean you are really at loss. Lets say I place a stop loss because I am already at profit and I want to make sure that my profits are protected even when I am not online and also to protect my profits on sudden price drop. Just make sure that your stop los order is not really that close to your Buy price because sometimes it sudden price drops triggers the sell order then price recovers right away.

i think 5-6 months ago binance posted a tweet that they were going to add 2 options at the same time stop loss and take profit.but i never heard anything about it after that.does anyone know anything?
