The number of grids in your price range will directly affect the % earnings between the two grid orders (buy and sell). Determining the optimal amount depends on your trading style and budget.
If you prefer to complete frequent trades with small profit % and guarantee the probability of filling orders - then you want to increase the number of grids.
In case your budget is limited or you want to receive more profit % per grid at the costs of lowering the chances of your orders get filled - then you want to decrease the number of grids.
For the best results, we recommend adjusting your profit per grid between 0.5% and 2%.
