Stormbreaker ADX - Supertrend and DMI Trend EA - sistema esperto per MetaTrader 5

Stormbreaker ADX is a MetaTrader 5 Expert Advisor that combines Supertrend direction with ADX strength and the +DI/−DI directional relationship. It evaluates signals on completed candles, sizes positions from a fixed equity-risk budget, and places an ATR-based protective stop.

The downloadable source is intended for study, testing and modification. The EA does not promise profits; test it with your broker's data and contract specifications before considering live use.

Figure 1. The entry filters are evaluated in sequence at the start of a new signal-timeframe candle.

1. Strategy overview

The default signal timeframe is H4. On each new H4 bar, the EA reads the previous completed bar (shift 1), calculates a custom Supertrend from ATR, and reads ADX, +DI, −DI and ATR values. A trade is considered only when the Supertrend direction and directional movement agree and ADX meets the entry threshold.

2. Entry and exit rules

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

3. Risk-based volume calculation

Before sending an order, Stormbreaker estimates the one-lot loss from the current Ask/Bid entry quote to the proposed stop using OrderCalcProfit . It divides the 0.5% equity risk budget by that estimated one-lot loss, then rounds the volume down to the broker's permitted volume step and applies the maximum-volume cap. It also checks available margin. If the minimum permitted lot would exceed the risk budget, or margin is insufficient, the EA skips the trade.

Excerpt simplified for explanation. The full source includes checks for invalid prices, tick/volume alignment, broker stop distances and margin. Because the stop is derived from the previous candle close while sizing uses the current entry quote, slippage/gaps and execution costs can make the realized loss differ from 0.5%. This is a risk target, not a guaranteed maximum loss.

Figure 2. Stop levels are ATR-based; the EA has no fixed profit target.

4. Inputs and defaults

The 0.5% risk percentage is currently a fixed constant in the source code, not a user input.

5. MQL5 signal code example

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); 

In the full EA, these conditions run only after detecting a new signal-timeframe bar and successfully retrieving the previous closed bar and indicator values.

7. Compatibility and practical use

• Platform: MetaTrader 5; source language: MQL5.
• Attach the EA to the chart of the symbol to trade; the signal timeframe is selected by SignalTimeframe .
• No external custom indicator files are required. The source uses the standard Trade\Trade.mqh library and built-in ATR/ADX data.
• Use a unique magic number for each EA instance. Avoid running other strategies or manual trades on the same symbol on netting accounts, where positions are aggregated.
• Test broker-specific minimum volume, tick size, stop-distance and margin requirements in Strategy Tester and on demo first.

8. NorthSlope: the next step

Stormbreaker ADX was an important step in my development of systematic trend-following EAs. NorthSlope is the definitive evolution of this work: a more focused Supertrend-based system for AAPL on H1, with rising-slope confirmation, an on-chart Supertrend display, detailed diagnostic logging and configurable equity-based risk sizing. NorthSlope is long-only and designed specifically for its stated AAPL setup; it is not a drop-in replacement for Stormbreaker's XAGUSD H4 configuration.

Risk notice: Automated trading involves substantial risk. A stop loss cannot guarantee the exit price in gaps or fast markets. Backtest, demo and historical results do not guarantee future outcomes. You are responsible for evaluating the EA and its settings before use.
