Grid trading is an automated system that allows you to trade following certain pre-set rules.
With Grid trading, you can set multiple prices for buy and sell and each transaction is triggered and completed automatically.
For, example, say you want to buy Bitcoin at $30k, and sell at $32k. But you also want to buy at $40k, and sell at $42k.
With Grid, you can set as many rules as you want.
The key feature of Grid is that you only need to set a price, and that's it.
