Hi
Tick staking is linked to the tick increment size.
If you want to win 1.00 per tick and current price is between 1.01 and 2.00, the tick increment in this range is 0.01.
Therefore 1/0.01=100 so your stake will be 100.00 for 1.00 profit per tick at this tick increment size
Price range 2.02 to 3.00: 1/0.02=50.00 stake at 0.02 increment size
etc.
variables are b_tick and l_tick
e.g. (your required profit per tick)/b_tick
