Assuming you open a long position with bitcoin at $90000, you will see the position as 1.
Also you open bitcoin long position at $91000, you should see the position as 2.
I means same coins with 2 positions. Just as if you open bitcoin as position 1 and another coin as position 2.
On most exchanges, the bitcoin amount you used to open 1st and 2nd position will add up as just only one position.
The reason I asked this question is because I want to try grid trading and this is how it can be convenient for me on a single exchange.
just make different accounts on DEX>
ApeX is one of my favorite, altho it cost money to pen accounts but they ask for no KYC what so ever.
I don't think there is any exchange that allow this.
