SignalBridge EA

Convert Compatible Indicator Signals Into Automated Trades

SignalBridge EA is a MetaTrader 4 Expert Advisor designed to connect compatible trading indicators with automated trade execution.

Instead of manually watching the chart and placing an order every time your indicator generates a BUY or SELL signal, SignalBridge EA can detect supported signals and automatically execute and manage the corresponding trade.

The EA supports several common methods used by MT4 indicators to communicate trading signals, including indicator buffers, chart arrows, chart objects, and text-based signals.

SignalBridge EA does not determine whether a third-party indicator's strategy is profitable. It acts as a signal-to-trade execution and trade-management tool.

Main Features

Multiple Signal Detection Methods

SignalBridge EA can work with many common MT4 indicator designs.

Supported methods include:

• BUY and SELL indicator buffers

• Single state buffers such as 1 = BUY and -1 = SELL

• Wingdings arrow objects

• Standard MT4 BUY/SELL arrows

• Standard MT4 UP/DOWN arrows

• Custom arrow codes

• BUY/SELL chart text

• LONG/SHORT chart text

• BULL/BEAR chart text

• UP/DOWN chart text

• BUY/SELL keywords contained in chart object names

• Combined signal detection

Because MT4 indicators can be programmed in many different ways, compatibility with every third-party indicator cannot be guaranteed.

Automated Trade Management

SignalBridge EA includes configurable trade-management features:

Stop Loss

Automatically places a Stop Loss based on the configured pip distance.

Take Profit 1

Sets the first profit target.

Take Profit 2

Provides a second profit target for the remaining position.

Partial Close

When TP1 is reached, the EA can close the configured percentage of the position and leave the remainder running toward TP2.

Breakeven

The remaining position can automatically be protected at breakeven after the configured conditions are reached.

Trailing Stop

The EA can trail the Stop Loss as the market continues moving in the trade's favor.

Magic Number

SignalBridge EA uses a Magic Number to identify and manage its own trades without intentionally managing unrelated EA positions.

Signal Modes

The SignalSource input determines how SignalBridge EA obtains its trading signals.

SIGNAL_INTERNAL_MA

Uses the EA's built-in EMA crossover signal.

This mode allows SignalBridge EA to operate independently without an external indicator.

The internal fast and slow EMA periods can be configured from the inputs.

SIGNAL_FROM_OBJECTS

Use this mode when your indicator creates arrows, labels, text, or other supported signal objects directly on the chart.

SIGNAL_FROM_DUAL_BUFFER

Use this when the indicator has separate buffers for BUY and SELL signals.

For example:

• Buffer 0 = BUY

• Buffer 1 = SELL

The buffer numbers can be changed from the EA inputs.

SIGNAL_FROM_STATE_BUFFER

Use this when a single indicator buffer represents both directions.

For example:

• 1 = BUY

• -1 = SELL

The expected BUY and SELL values are configurable.

SIGNAL_FROM_ALL

Allows SignalBridge EA to check the supported external signal methods together.

Use this mode carefully to avoid multiple methods representing the same indicator signal.

How to Install SignalBridge EA

Step 1 — Install the EA

Open MetaTrader 4.

Select:

File → Open Data Folder

Then open:

MQL4 → Experts

Place SignalBridge EA in the Experts folder.

Restart MetaTrader 4 or refresh the Expert Advisors section in the Navigator.

Step 2 — Install Your Indicator

If you are using SignalBridge EA with a third-party custom indicator, install that indicator normally.

Open:

File → Open Data Folder → MQL4 → Indicators

Place the indicator in the Indicators folder.

Restart MetaTrader 4 or refresh the Navigator.

Step 3 — Open a Chart

Open the symbol and timeframe you want to trade.

For example:

EURUSD — M15

Attach your signal indicator to the chart first when using chart-object signals.

Then attach SignalBridge EA to the same chart.

Step 4 — Enable Automated Trading

Make sure AutoTrading is enabled in MetaTrader 4.

When attaching SignalBridge EA, open the Common tab and enable:

Allow live trading

The AutoTrading button at the top of MT4 should also be enabled.

Using an Arrow Indicator

If your indicator draws BUY and SELL arrows directly on the chart, select:

SignalSource = SIGNAL_FROM_OBJECTS

The default settings scan supported chart arrows, text objects, and object names.

If your indicator uses special Wingdings arrow codes, enter the appropriate codes in:

ArrowCodeBuy

ArrowCodeSell

Alternative codes can also be configured.

Using an Indicator With BUY/SELL Buffers

If your indicator uses two separate buffers, select:

SignalSource = SIGNAL_FROM_DUAL_BUFFER

Then enter the indicator name.

Example:

IndicatorName = MySignalIndicator

Do not include .ex4 .

Configure:

BufferBuy = 0

BufferSell = 1

These are only examples. You must use the actual buffer numbers used by your indicator.

Using a Single Signal Buffer

For indicators where one buffer contains the trading direction, select:

SignalSource = SIGNAL_FROM_STATE_BUFFER

Example configuration:

StateBuffer = 0

StateBuyValue = 1.0

StateSellValue = -1.0

Change these values if your indicator uses a different convention.

BUY and SELL Keywords

SignalBridge EA can search supported chart text and object names for signal words.

Default BUY-related keywords include:

buy, long, bull, up

Default SELL-related keywords include:

sell, short, bear, down

These keywords can be adjusted to match the terminology used by your indicator.

SignalShift

SignalShift = 1 is recommended.

A value of 1 tells SignalBridge EA to evaluate the last closed candle where applicable.

This can help prevent acting on an unfinished current candle whose signal may still change.

Invert Signals

The InvertSignals option reverses detected signals.

When disabled:

BUY signal → BUY trade
SELL signal → SELL trade

When enabled:

BUY signal → SELL trade
SELL signal → BUY trade

Leave this option disabled unless your strategy specifically requires reversed signals.

Trading Settings

LotSize

Sets the requested trading volume.

Example:

LotSize = 0.10

Always select a position size appropriate for your account and risk tolerance.

StopLoss

Stop Loss distance in pips.

Example:

StopLoss = 30

TakeProfit1

First profit target in pips.

Example:

TakeProfit1 = 50

TakeProfit2

Second profit target in pips.

Example:

TakeProfit2 = 100

PartialClosePercent

Percentage of the position to close at TP1.

Example:

PartialClosePercent = 50

This means the EA attempts to close 50% of the position when TP1 is reached, subject to the broker's minimum lot size and lot-step requirements.

BreakevenAfterTP1

When enabled, SignalBridge EA can protect the remaining position with a breakeven Stop Loss after TP1.

BreakevenOffset

Controls the configured offset from the entry price when breakeven protection is applied.

UseTrailingStop

Enables or disables trailing-stop management.

TrailingStop

Sets the trailing distance.

TrailingStep

Controls the minimum step used when updating the trailing Stop Loss.

SlippagePoints

Sets the permitted order-execution slippage in points.

Example Setup

Suppose you have an indicator that:

• Places a green upward arrow for BUY

• Places a red downward arrow for SELL

• Creates those arrows as chart objects

A typical setup would be:

SignalSource = SIGNAL_FROM_OBJECTS

SignalShift = 1

ScanArrowObjects = true

LotSize = 0.10

TakeProfit1 = 50

TakeProfit2 = 100

StopLoss = 30

PartialClosePercent = 50

BreakevenAfterTP1 = true

UseTrailingStop = true

Once the indicator creates a supported new BUY or SELL signal, SignalBridge EA can detect it and execute the corresponding trade according to your settings.

Important Compatibility Information

SignalBridge EA is designed to support many common MT4 signal indicators, but it cannot guarantee compatibility with every indicator.

Some indicators use proprietary internal calculations without exposing their signals through accessible buffers or chart objects. Others require special parameters when accessed through iCustom() .

If an indicator does not expose its signal in one of the supported formats, additional configuration or modification may be required.

For buffer-based indicators, users should know the indicator's BUY/SELL buffer numbers or signal values.

Important Trading Information

SignalBridge EA is a trade-execution and management tool.

The quality and profitability of trades depend heavily on:

• The connected indicator

• Indicator settings

• Symbol

• Timeframe

• Market conditions

• Spread and execution

• Stop Loss and Take Profit configuration

• Risk and lot-size settings

SignalBridge EA does not guarantee profits.

Always test your indicator and SignalBridge EA combination on a demo account and in appropriate testing conditions before using it on a live account.
