What's the difference between a free account and Professional?
Everyone sees the same data. Professional adds higher limits: more tags, external notifications, more live market pages at once and longer chart history.
What's the same
Spreads, funding rates, deposits and withdrawals, coins, earn and borrow data are the same on a free account and on Professional. Web alerts, pairing with ZML Trade and sending opportunities to Trade don't need a subscription either.
What Professional adds
More opportunity tags.
External notifications: alerts sent to Telegram or Feishu, plus deposit and withdrawal resumed alerts.
More live market pages open at the same time.
Chart history that goes back more days.
Compare each limit and the price in the plans window. To subscribe and pay, see Subscription and payment.
When it expires
When Professional expires, you return to a free account. Your first tag keeps working, the other tags are locked with their settings kept, and external notifications stop while your channels are kept. Renew to restore everything as it was. You can turn off auto-renew any time in My plan, and the current period still runs until it ends.
