Creating a Position
Once you have the hub's address, you can now create your position. Take into account that:
  • from and to need to be different tokens
  • amount must be a positive number
  • amountOfSwaps must be a positive number
  • swapInterval must be one of the allowed swap intervals. There is a list of pre-defined supported time intervals, but the hub has a configuration that determines which are allowed and which are not. The supported time intervals are:
    • 1 minute
    • 5 minutes
    • 15 minutes
    • 30 minutes;
    • 1 hour
    • 4 hours
    • 1 day
    • 1 week
