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
