If you input the Base Order Size and Max. n. of positions, Mizar calculates what is the maximum amount of assets that the bot can invest at a single time. This is calculated as the Base Order Size multiplied by the Max. n. of positions opened at a single time.
If you input the Maximum Investment, instead, Mizar calculates back what Base Order Size and Max. N. of Positions you need to invest that Maximum amount.
How is the Maximum Investment (API Bots) calculated?
If your base order is 100 USDT and your max n. of positions is 10, your Maximum Investment will be 100x10=1000USDT. That means, at a single point in time, you could have 1000 USDT in open positions.
