You are correct that some information is missing, and I'm happy to help you define it. To give you an accurate quote, I would need to know the following key details:
1. The Exact Trading Strategy (The "Rules") This is the most important part. "Candlestick movements" is a great start, but I need the exact, mechanical rules for the EA to follow. For example:
"IF a 5-minute candle closes as a 'Doji' AND the 10-period Moving Average is trending up, THEN enter a 'HIGH' (Call) trade."
"IF the RSI(14) indicator crosses below 30 AND the price is below the lower Bollinger Band, THEN enter a 'LOW' (Put) trade."
I would need to know:
What indicators are used (e.g., Moving Average, RSI, Bollinger Bands)?
What are the specific conditions (e.g., "price closes above MA," "RSI is over 70")?
What timeframe will it run on (M1, M5, M15)?
What is the expiry time for each trade (e.g., 60 seconds, 5 minutes, end of the next candle)?
2. The Trading Platform Am I correct to assume this will be for MetaTrader 4 (MT4), like the indicator we just built?
3. The Automation Method (Very Important) This is the biggest technical challenge for binary options. How will the EA send the trade to your binary options broker?
Option A: Alerts Only (Simple) Does the EA just need to pop up an alert on your chart (e.g., "EURUSD - PLACE 'HIGH' TRADE NOW"), and then you will place the trade manually? (This is the simplest and most likely to fit your budget).
Option B: Full Automation (Complex) If you want the EA to place the trade for you, we need to know:
Which binary options broker do you use?
Does this broker offer a special MT4 platform or plugin that can receive trading commands from an EA? (This is very rare).
Does the broker offer an API? (This is much more complex and would likely exceed your budget).
Please think about these three points, especially the Trading Strategy and the Automation Method.
