SL Double Quantity Order On Reversal

Hello,

I’ve been trying to figure out something about the SL order and can’t seem to speculate the outcome. Please read below to know the scenario.

LTP = 200

Now, I want to place a Buy Order above LTP and for this I’ll be using an SL Buy Order.
The parameters for SL Buy order are as follows,
Trigger Price = 210
Price = 211
Quantity = 1

Later when the SL Buy order gets executed I will place a new SL Sell Order to exit the position. But along with exiting the position, I also want to place a new Sell Position right where the Buy Order was exited.
The parameters for SL Sell order are as follows,
Trigger Price = 190
Price = 189
Quantity = 3

Since I mentioned the quantity as 3, what will happen when the the SL Sell order is triggered?

Will it square-off my buy position and automatically continue with a sell position of quantity 2?

Please can someone clarify this confusion
