How often does the ExchnageInfo get's updated

API Spot/Margin API

Hi

I have asked this question before but have not received any answer, searching the internet, Binance etc. have not really given an clear answer and ChatGPT say something like this:

“If you’re building a trading bot, checking the exchangeInfo data at least once per hour should suffice unless Binance releases critical updates requiring immediate action.”

Is there any official information on this subject ?

Thanks

Hi @rabol, the exchangeInfo data on Binance is updated whenever there are changes to the exchange’s trading rules, symbols, or trading pairs. These updates are not on a fixed schedule but typically occur in the following scenarios:

  • New Symbol Listings: When Binance adds new trading pairs or assets.
  • Symbol Delistings: If a trading pair is removed.
  • Trading Rule Updates: Changes to filters, precision, or limits (e.g., minimum order size, maximum price).

To stay informed you can always do the following:

  • Monitor Binance announcements for updates related to trading pairs or rules.
  • For most use cases, checking exchangeInfo once per day is generally sufficient unless you anticipate frequent changes or rely on up-to-the-minute accuracy.

If your application requires real-time precision and filters, you might consider fetching exchangeInfo more frequently (e.g., once per hour) or whenever you notice unusual behaviour/errors (like a rejected order due to filter mismatches).
