The difference between short and long options in trading refers to the direction in which you expect the price of an asset to move. A long position is taken when you expect the price to rise, while a short position is taken when you expect the price to fall. In the context of the Grid bot trading strategy, you can use the short and long options with manual settings to specify the direction of your trades. Short trades can be used to profit from falling prices, while long trades can be used to profit from rising prices.

Note: The Grid bot can only operate long-term strategies, as the short-selling function is currently being worked on, so stay tuned!
