Trading Signals

Trading signals define when your Expert Advisor should open or close positions. Learn how to create powerful entry and exit conditions.

What Are Trading Signals?

Signals are conditional rules that trigger trading actions. They compare values (indicator outputs, price, account metrics) using comparison operators.

Signal Types

Open Buy Signals

Conditions that trigger opening a buy (long) position. Example: "Open buy when RSI crosses above 30"

Open Sell Signals

Conditions that trigger opening a sell (short) position. Example: "Open sell when RSI crosses below 70"

Close Buy Signals

Conditions that trigger closing existing buy positions. Example: "Close buy when profit exceeds 50 pips"

Close Sell Signals

Conditions that trigger closing existing sell positions.

Building a Signal

A signal consists of three parts:

  1. Left Value: What to compare (indicator output, price, etc.)
  2. Operator: How to compare (greater than, less than, equal, etc.)
  3. Right Value: What to compare against (another indicator, constant, price, etc.)

Example Signal

RSI.Value > 30
  • Left Value: RSI indicator output
  • Operator: Greater than (>)
  • Right Value: Constant (30)

Value Types

Indicator Values

Reference any output from your configured indicators. Each indicator may have multiple outputs (e.g., MACD has Main, Signal, and Histogram).

Price Values

Current market prices:

  • Open, High, Low, Close
  • Bid, Ask

Account Values

Account metrics:

  • Balance
  • Equity
  • Profit

Order Values

Position information:

  • Open Positions Count
  • Current Position Profit

Constant Values

Fixed numbers for comparison (e.g., 30, 70, 1.5, etc.)

Comparison Operators

  • > Greater than
  • >= Greater than or equal
  • < Less than
  • <= Less than or equal
  • == Equal
  • != Not equal

Signal Evaluation Strategies

When you have multiple signals, choose how they should be evaluated:

All Signals (AND)

All signals must be true for the action to trigger. Use this for strict entry conditions.

Any Signal (OR)

At least one signal must be true. Use this for flexible entry with multiple strategies.

At Least N Signals

A minimum number of signals must be true. Good for confirmation strategies.

Example Strategies

RSI Oversold/Overbought

Open Buy:  RSI < 30
Close Buy: RSI > 70

Moving Average Crossover

Open Buy:  MA_Fast > MA_Slow
Open Sell: MA_Fast < MA_Slow

Multi-Indicator Confirmation

Open Buy (All signals):
  - RSI > 50
  - MACD.Main > MACD.Signal
  - Close > MA_20
Tip: Start with simple signals and add complexity gradually. Test each signal thoroughly before combining them.
