Depending on the algorithms used a commission between 0.3% - 1.8% is charged for starting and stopping the algorithms. Arkady 0.3% | Balthazar 1.8% | Kaspar 1.3% | Melkior 0.9%
When your algorithmic positions are closed with profits a standard 18% fee is charged in the GRAYLL GRX digital asset on the profits only, not the principal amount. There are no other costs for using the GRAYLL System, of course you must have the GRAYLL GRX digital asset which can be purchased directly in the GRAYLL App with XLM (Stellar Lumens). Transferring GRX and XLM between accounts over the Stellar Network has a negligible cost of 0.00001 XLM (~$0.00000045) per transaction.
