Stormbreaker ADX - Supertrend and DMI Trend EA for MT5

Related: Supertrend Scalper with Breakeven Win Rate Panel - another powerful expert for MetaTrader 5 traders.

Stormbreaker ADX is a MetaTrader 5 Expert Advisor that integrates Supertrend direction with ADX strength and the +DI/−DI directional relationship. It assesses signals on completed candles, manages position sizing based on a fixed equity-risk budget, and implements an ATR-based protective stop.

Also recommended: Night Flat Trade Strategy - similar expert with strong performance on MetaTrader 5.

The downloadable source code is provided for educational purposes, testing, and modification. This Expert Advisor does not guarantee profits; thorough testing with your broker's data and contract specifications is essential before considering live deployment.

1. Strategy Overview

The default signal timeframe is H4. For each new H4 bar, the EA analyzes the preceding completed bar (shift 1), computes a custom Supertrend using ATR, and reads ADX, +DI, −DI, and ATR values. A trade is initiated only when the Supertrend direction and directional movement indicators align, and the ADX meets the specified entry threshold.

Component

Default

Purpose

Signal timeframe

H4

Signal evaluation timeframe; entries are checked once per new bar.

Supertrend

ATR 10, factor 3.0

Defines the current trend direction.

ADX / DMI

ADX 14; entry threshold 23

Filters for trend strength and confirms direction using +DI and −DI.

Exit strength threshold

ADX below 18

Closes a managed position when trend strength weakens below the exit level.

Initial stop

2 × ATR(10)

Places the stop from the completed signal bar's close, then aligns it to broker price rules.

Risk budget

0.5% of current equity

Calculates volume from the estimated loss between the current entry quote and stop.

Take profit

None

There is no fixed take-profit target; exits are signal/strength based or by stop loss.

2. Entry and Exit Rules

Action

Conditions

Open a buy

Buy entries enabled; Supertrend is bullish; ADX ≥ 23; +DI > −DI.

Open a sell

Sell entries enabled; Supertrend is bearish; ADX ≥ 23; −DI > +DI.

Close an existing position

ADX < 18, or Supertrend direction reverses against the position. An opposite qualifying signal also closes/reverses the managed position.

The EA does not add to a same-direction position if an existing position with the same symbol and magic number is found. A stop-loss remains active independently of the signal exit.

3. Risk-Based Volume Calculation

Prior to sending an order, Stormbreaker estimates the potential loss for a one-lot trade from the current Ask/Bid entry quote to the proposed stop level using OrderCalcProfit. It then divides the 0.5% equity risk budget by this estimated one-lot loss. The resulting volume is rounded down to the broker's permitted volume increment and capped by the maximum volume setting. Margin availability is also verified. If the minimum allowable lot size would exceed the risk budget or if margin is insufficient, the EA will skip the trade.

double risk_cash = AccountInfoDouble(ACCOUNT_EQUITY) * 0.5 / 100.0; double one_lot_loss = MathAbs(one_lot_profit); double volume = MathFloor((risk_cash / one_lot_loss) / volume_step) * volume_step; volume = MathMin(volume, MaxVolume);

Excerpt simplified for explanatory purposes. The complete source code includes checks for invalid prices, tick/volume alignment, broker stop distance rules, and margin requirements. Due to the stop being derived from the previous candle's close while sizing utilizes the current entry quote, potential slippage, price gaps, and execution costs can result in the realized loss deviating from the 0.5% target. This represents a risk target, not a guaranteed maximum loss.

Figure 2. Stop levels are determined by ATR; the EA does not feature a fixed profit target.

Minimum ADX value required for initiating a new trade entry.

ExitADX

18.0

ADX level below which an open position will be closed.

StopATRMultiple

2.0

ATR multiple used to determine the initial stop-loss distance.

MagicNumber

51003

The 0.5% risk percentage is currently a fixed constant within the source code and is not exposed as a user input.

5. MQL5 Signal Code Example

The subsequent excerpt illustrates the closed-bar entry conditions implemented by the EA:

bool long_signal = EnableBuy && direction < 0
&& adx >= EntryADX && plus_di > minus_di;
bool short_signal = EnableSell && direction > 0
&& adx >= EntryADX && minus_di > plus_di;

if(long_signal)
STOpenPosition(true, bar.close - StopATRMultiple * atr,
0.0, MagicNumber, "ST ADX long", MaxVolume,
DeviationPoints);
else if(short_signal)
STOpenPosition(false, bar.close + StopATRMultiple * atr,
0.0, MagicNumber, "ST ADX short", MaxVolume,
DeviationPoints);
else if(position != 0 && (adx < ExitADX
|| (position > 0 && direction > 0)
|| (position < 0 && direction < 0)))
STClosePosition(MagicNumber);

Within the full EA implementation, these conditions are evaluated only after detecting a new signal-timeframe bar and successfully retrieving the prior closed bar and indicator data.

6. Broker Backtest Snapshot

The following figures are derived from the provided MetaTrader 5 Strategy Tester reports for XAGUSD on H4. As initial deposits vary, both net return and net profit are presented. Tick-history quality is also variable, with particularly limited data for Fusion Markets.

Testing Limitations:

The presented results are from historical Strategy Tester runs and do not represent audited live trading performance. The reported periods conclude on slightly different dates, and initial deposits and broker specifications vary. Modeling quality ranges from 4% to 41% real ticks. These figures are not directly comparable and do not serve as a predictor of future outcomes. It is recommended to conduct your own tests with your intended broker, symbol specifications, spread, commissions, swaps, and tick data.

7. Compatibility and Practical Use

Platform: MetaTrader 5; Source Language: MQL5.

Attach the EA to the chart of the desired trading symbol. The signal timeframe is configured via the SignalTimeframe input parameter.

No external custom indicator files are required. The EA utilizes the standard Trade rade.mqh library and built-in ATR/ADX indicator data.

Employ a unique Magic Number for each EA instance. On netting accounts, where positions are aggregated, refrain from running other strategies or executing manual trades on the same symbol.

Verify broker-specific minimum volume, tick size, stop distance, and margin requirements in the Strategy Tester and on a demo account prior to live trading.

8. NorthSlope: The Next Step

Stormbreaker ADX represented a significant milestone in the development of my systematic trend-following Expert Advisors. NorthSlope is the definitive evolution of this work. It is a more focused Supertrend-based system designed for AAPL on H1, incorporating rising-slope confirmation, an on-chart Supertrend display, detailed diagnostic logging, and configurable equity-based risk sizing. NorthSlope is long-only and specifically tailored for its stated AAPL setup; it is not a direct substitute for Stormbreaker's XAGUSD H4 configuration.

Risk Disclosure:
Automated trading systems carry substantial risk. A stop-loss order cannot guarantee execution at the specified price during market gaps or periods of high volatility. Backtest results, demo trading, and historical performance do not ensure future profitability. You are solely responsible for evaluating the Expert Advisor and its settings before deployment.
