I saw one Octa review in which trader listed advantages of Octatrader platform and apparently it's a really cool platform
But you can consider me old-fashioned because I chose MetaTrader 4 platform :D
Yes, Octa provides several platforms to choose from. And I chose MT4 because I was used to its interface.
If you are not like me, then you can try Octatrader, it's also a great platform
