Paid version is focused on:
Traders — active users, working both on short and long positions. They perform numerous transactions and may have several active. Unlike the "Individual investors", traders perform series of transactions: several transactions within the same currency - purchase, exchange, transfer, withdrawal. They need to keep a record of these transactions and be able to see the overall statistics. Moreover, it is important to automate the addition of transactions.
Funds (manage) — in other words, traders who take third-party finance under management and supervise several clients. They need to be able to separate the agent and client accounts, and actively interact with the technical support for individual improvements. The agent account will feature the possibility of setting the client cabinet for each separate client: displaying the relevant information, placing a personal logo, generating a report, etc.

We are going to present our competitive advantages in a more detailed form in the near future.
