You can look at this article : https://www.pionex.com/blog/knowledge-base/how-to-set-up-the-parameters-for-my-first-grid-bot/
Quantity per grids means the amount of tokens that will be put on each buy orders and sell orders.
Grid number means the number of grid will be used. Similar like if you are using 1000-2000 price range, how many part you want to divide this range is.
Trigger Price means the price where you want the bot start. The bot only start if the market price touch this trigger price. You can use this feature to make a delayed bot instead of instant bot.
