Hello,
Let us assume present order book looks like below
Bid
Price Order Quantity
1.1 1 100
0.9 10 10000
0.8 12 2300
suppose my is the only order at 1.1 of 100 quantity.
Now suppose 5 more orders are placed at 1.1 and the scenerio is as follows:
Bid
Price Order Quantity
1.1 6 10000
0.9 10 10000
0.8 12 2300
Now i am at the first place is someone sells at 1.1 i will be the one who’s order will be executed.
Now if i modify the order to increase the quantity to 1000 will i be shifted to last or i will be at the first position only?
