DCA Spot Buy (One-Shot)

Config

• Trading pair (required): Symbol (e.g. BTC/USDT). Base is bought with the quote asset.
• Quote amount per buy (e.g. USDT) (required): How much of the quote asset to spend on this buy.
• Binance API (required): Used to place the order.
• Telegram (optional): If set, a summary message is sent after the order (symbol, quote amount, approximate price, order id).

Logic

1. Read symbol and quote amount; fetch current ticker for the pair (for the notification).
2. Place a spot market buy with the given quote order quantity.
3. If Telegram is configured, send one message with the result.
4. Finish with order details and last price.

When it stops: After one run (single DCA execution). To run periodically, schedule this workflow externally (e.g. cron).

If something fails: Errors (e.g. insufficient balance, API error) propagate.
