Dollar-Cost-Averaging (DCA) Bots allow you to automatically buy and/or sell crypto at regular intervals. Once a Base Order is open, the bot will open Safety Orders when the price goes against your expectations. This will allow you to improve your average entry size.
Each DCA bot has fixed rules which determine when the Safety Orders have to be triggered and how (size and number). That means, once a new Base Order is open, the DCA bot will monitor conditions and open (add on top to the Base Order) new Safety Orders, if the conditions are met.
The maximum investment is what would be deemed the "worst-case scenario": when all the Safety Orders conditions are met and all the Safety Orders are open at a single time - by no means does this mean that things cannot always go further down, so always be diligent with your investments.
The Maximum Investment can substantially differ from the Expected Investment and it is a way to measure the maximum exposure the bot could bring.
How is the Maximum Investment calculated?
If you input 100 USDT and the max n. of positions is 10, and the bot is allowed to open up to 5 safety orders (with the same size as the base order), your max investment will be 100x10x5=5000 USDT. That means, at a single point in time, you could have 5000 USDT open positions.
