The number of orders in the grid depends on the deposit of the allocated bot. A deposit should be sufficient to create all of the grid of orders.
We usually recommend a deposit that is no less than 300-400USD and the number of orders at that time is 15-20.
The Martingale percentage sets by how much the volume of each subsequent order of the grid will be greater than the previous one. The more Martingale percentage you have, the less of a rebound you’ll need to get a take-profit order. The bigger the Martingale percentage, the smaller the first orders of the grid, which reduces profit but also reduces risk. We usually recommend a Martingale percentage of at least 3-5%. With large deposits, you can increase your Martingale percentage to 10%.
