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.
You can not if you use only one account.
It's possible if you use multiple accounts on one exchange, like you use a first account with trading positions used x2 leverage; a second account for trading positions with x5 leverages; and a third account with trading positions used x10 leverages.
By using different accounts and different leverages, you can manage your entry and exit as well as risk better. I mean you can calculate your entry, exit and liquidation price better, but this method contains risk of exchange policy. Using multiple accounts are likely not accepted by their ToS.
I have used Binance, OKX, Bybit, Kucoin, HTX, BitMart, BitMez, Bitget, MEXC and few other exchanges before but I have not seen such feature before on exchanges.
If you already used different exchanges, you can avoid risk of ToS violation by multiple accounts on one exchange easily. It's an approach to use different accounts on different exchanges with different leverages.
For example: Binance (2x leverage), OKX (5x leverage) and Bybit (10x leverage).
Does it make sense with you?
