You can try and evaluate GridBot in work completely free of charge. To do this, you need to perform all the actions from the page https://www.gridbot.info/en/start  

The bot will work up to the first 100 trades on each trading symbol, then it will be stopped. You can create several bots on different trading pairs - the limit of 100 deals is valid for each pair separately. If after stopping you buy a license, the bot will continue to work within the time specified in the license.

More information about different licenses can be found at https://www.gridbot.info/en/license
