For example, if the price range is 100-400, and you set the grid quantity to 3 with arithmetic mode, it would create three grids: 100-200, 200-300, and 300-400. Grid mode: Arithmetic: maintains a consistent difference between each grid level (e.g., 1, 2, 3, 4). Geometric: maintains a consistent ratio between each grid level (e.g., 1, 2, 4, 8). Investment amount: this is the total amount of the selected currency the bot will use to place buy and sell orders across the grids.
