Symbol Synchronization

• SyncBinanceSymbolTaskFirstStart() runs when the application is started for the first time and fetches the symbols.
• It retrieves all available trading pairs from the exchange’s API and matches them with the assets in the database.
• If there are missing symbols in the database, the syncBinanceSymbol() function is called to add the missing ones.
• After this process is complete, SyncBinanceSymbolsTask() updates the symbols weekly.

Wallet Synchronization

• SyncBinanceWallet(): Runs every second to check the current balances.
• syncBalances(): Fetches and updates the user’s balances from the Binance API.
• saveBalances(): Saves or updates the user’s balances in the database.

Order Synchronization

• CheckBinanceOrdersStatus(): Checks the status of open orders.
• CheckBinanceOpenOrders(): Updates the open orders.

• saveTrades(): Saves or updates the user’s buy-sell trades in the database.
  • If a trade is updated, the wallet balances are refreshed with the SyncBinanceWallet() function.
