Ethereal-Maker-BBO-with-Stop-Loss

Who is this for?

This workflow is designed for active traders and DeFi participants who want to automate their trading strategy on Ethereal. It suits users who prefer systematic, indicator-based trading decisions and want to manage risk with stop loss protection while maintaining flexibility through maker orders at best bid/offer prices.

What problem is this workflow solving? / Use case

Manual trading requires constant monitoring of market conditions, technical indicators, and order execution. This workflow automates the entire process:

• It analyzes market trends using multiple technical indicators (ADX, Bollinger Bands, Supertrend) to determine optimal entry direction.
• It places maker orders at best bid/offer prices to minimize slippage and capture better execution prices.
• It automatically manages positions with stop loss protection to limit downside risk.
• It ensures complete order execution by falling back to market orders if limit orders don't fill, preventing partial fills from leaving positions unhedged.

What this workflow does

1. Fetches OHLCV kline data from Aster for the configured symbol and removes the latest unfinished candle to avoid repaint noise.
2. Calculates technical indicators:
   • ADX (via callTAIndicator) to measure trend strength.
   • ATR for volatility context that feeds Supertrend and Bollinger Bands.
   • Bollinger Bands for mean-reversion signals.
   • Supertrend for trend-following signals.
3. Pulls the current ticker price from Aster to compare against indicator signals.
4. Uses ADX >= 25 as the "strong trend" gate:
   • Strong trend (ADX >= 25) → follows Supertrend direction for trend-following entry.
   • Weak trend (ADX < 25) → compares price vs. Bollinger middle band for mean-reversion entry.
5. Determines trade direction (BUY/SELL) based on the selected strategy.
6. Places a maker order at best bid/offer price using placeMakerBBO with the configured size.
7. If the maker order is filled, places a limit order with stop loss protection using placeLimitOrderWithStopLoss to take profit and limit downside risk.
8. If the limit order filled is 0 (didn't fill), automatically executes a market order for the remaining quantity to ensure complete position management.

Setup

1. Symbol – Set the trading pair symbol in the config node (default BTC). Use the format supported by Ethereal (e.g., BTC, ETH).
2. Size – Define the order size as a string (default 0.001). Adjust based on your risk tolerance and account size.
3. Interval – Set the kline interval for technical analysis (default 4h). Common options include 1h, 4h, 1d.
4. Order Book Level – Specify which order book level to use for maker orders (default 5).
5. Polling Interval – Set the polling interval in milliseconds for order status checks (default 10000).
6. Profit Offset – Define the profit target offset price (default 6). This determines how far above/below the entry price the limit order will be placed.
7. Stop Loss Offset – Define the stop loss offset price (default 100). This determines how far below/above the entry price the stop loss will trigger.
8. Timeout – Set the timeout in milliseconds for limit order execution (default 90000).
9. Proxy (optional) – Provide a proxy URL if you need to route traffic through a specific endpoint.
10. Ethereal credentials – Select the managed ethereal credential so the workflow can access ethereal_signerKey, ethereal_subAccountId, ethereal_subAccountName, and ethereal_accountAddress.
11. Deploy or schedule the workflow (cloud scheduling is handled externally per the workflow rules).
