To start trading, you need to register on the exchange and deposit funds on it.
(instructions for replenishing the account are available on all exchanges).
Then, connect to the Letit terminal using Api-keys (step-by-step help is in our tutorial video here).
Let us remind you that Letit terminal is a trading tool on the exchange. It does not store or use your funds, does not trade for you, and does not give advice on choosing a strategy.
