As an MQL developer, I’ve spent years constructing buying and selling robots. All of us chase the identical factor: a system that’s each clever and strong. We depend on technical indicators, worth motion, and sophisticated logic to seek out an edge. For a very long time, Machine Studying felt like a “holy grail,” however one which was simply out of attain or an excessive amount of of a “black field.”
My fundamental hesitation was this: I do not need an EA that *simply* depends on a blind prediction. The market has context. A mannequin educated on historic knowledge may say “BUY,” however as a dealer, I do know that sign is nugatory if the unfold is 100 pips, volatility is zero, or a serious development on the next timeframe is screaming “SELL.”
So, I made a decision to construct one thing totally different: a Hybrid EA. An EA that makes use of a robust Machine Studying mannequin for its core sign however then validates that sign towards a gauntlet of confirmed, “commonsense” technical confluence filters.
Right this moment, I wish to stroll you thru the precise course of I used to construct this, from a Python script to a totally useful MQL5 Professional Advisor.
Half 1: The ML Workflow – From Information to Mannequin
You may’t simply “make” an AI. You must practice it. This whole a part of the method occurs exterior of MetaTrader, usually in Python utilizing libraries like TensorFlow (Keras) and Scikit-learn.
1. Information Preparation & Function Engineering
First, I wanted knowledge. A lot of it. I exported historic knowledge (Open, Excessive, Low, Shut, Tick_Volume) for my goal image. The important thing is not simply the information, however the way you body the issue. I am not making an attempt to foretell the *actual* subsequent worth; I am making an attempt to foretell a easy binary consequence: “Will the subsequent bar’s Shut be greater or decrease than the present bar’s Shut?”
I structured this as a “windowed” dataset. The mannequin would have a look at a sequence of 60 bars ( WINDOW_SIZE = 60 ) to foretell the result of the 61st bar.
2. Normalization (The Essential Step)
Neural networks do not like uncooked worth knowledge. A worth of 2300.00 is only a “massive quantity” and might trigger the mannequin’s math to blow up. We should normalize all our options, normally to a spread between 0 and 1. I used an ordinary `MinMaxScaler`.
That is vital: you could save the *actual* parameters (min, max, scale) used to normalize the coaching knowledge. We’ll want them inside MQL5 to organize stay market knowledge for the mannequin.
<!– PSEUDO-CODE: Saving the Scaler (Python) –> scaler = MinMaxScaler(feature_range=(0, 1)) X_train_scaled = scaler.fit_transform(X_train) # — Save the scaler parameters — # That is the “secret key” for our EA save_scaler_to_file(scaler, “my_scaler.pkl”)
3. Mannequin Coaching (Python/TensorFlow)
I used a easy however highly effective LSTM (Lengthy Brief-Time period Reminiscence) community. LSTMs are nice at understanding sequences, which is ideal for time-series knowledge like charts.
<!– PSEUDO-CODE: Mannequin Coaching (Python) –> # ‘y_train’ is 1 if next_close > shut, else 0 mannequin = Sequential([ LSTM(units=50, input_shape=(60, 5)), # 60 bars, 5 features Dropout(0.2), Dense(units=1, activation=’sigmoid’) # Final output: 0.0 to 1.0 ]) mannequin.compile(optimizer=”adam”, loss=”binary_crossentropy”) mannequin.match(X_train_scaled, y_train, epochs=30) # Save the educated mannequin mannequin.save(“My_Gold_Model.h5”)
The `sigmoid` activation is essential. It means the mannequin’s output is not simply “BUY” or “SELL,” however a likelihood from 0.0 (100% likelihood of DOWN) to 1.0 (100% likelihood of UP). A price of 0.5 is impartial.
4. Conversion to ONNX
MetaTrader 5 cannot run TensorFlow fashions straight. It runs fashions within the ONNX (Open Neural Community Change) format. It is a easy conversion step utilizing a Python library.
<!– PSEUDO-CODE: Conversion (Shell) –> # This one-liner converts our Keras mannequin to ONNX !python -m tf2onnx.convert –keras My_Gold_Model.h5 –output My_Gold_Model.onnx
Now I’ve two important information: My_Gold_Model.onnx and the scaler parameters (which I exported to a easy CSV file).
Half 2: The MQL5 Integration – Constructing the Hybrid EA
That is the place the magic occurs. We convey our educated mannequin into MQL5.
1. Loading the Mannequin and Scaler
I embed each the `.onnx` file and the scaler knowledge straight into the EA’s code utilizing #useful resource . In OnInit() , the EA masses the mannequin into reminiscence and parses the scaler values into a worldwide array.
<!– PSEUDO-CODE: MQL5 OnInit() –>
#useful resource “RecordsdataMLModelsMy_Gold_Model.onnx” as const uchar Model_M5[]
#embody <Commerce/Commerce.mqh>
lengthy g_modelHandle = INVALID_HANDLE;
double g_scalerMin[5]; // open, excessive, low, shut, quantity
double g_scalerScale[5];
int OnInit()
{
// … load scaler values from useful resource into g_scalerMin/g_scalerScale …
// Load the ONNX mannequin from the useful resource buffer
g_modelHandle = OnnxCreateFromBuffer(Model_M5, ONNX_DEFAULT);
if(g_modelHandle == INVALID_HANDLE)
{
Print(“Didn’t load ONNX mannequin!”);
return(INIT_FAILED);
}
return(INIT_SUCCEEDED);
}
2. The Prediction Loop (OnTick)
On each tick (or new bar), the EA does the *very same course of* as our Python script:
Will get the final 60 bars of knowledge. Normalizes this knowledge utilizing our saved g_scalerMin and g_scalerScale values. Passes the 60×5 normalized matrix to the ONNX mannequin. Will get a single float worth again (our likelihood).
<!– PSEUDO-CODE: MQL5 OnTick() Prediction –> void OnTick() { // 1. Get final 60 bars MqlRates charges[]; CopyRates(_Symbol, _Period, 0, 60, charges); // 2. Normalize knowledge matrixf input_data(60, 5); for(int i=0; i<60; i++) { input_data[i][0] = (float)((charges[i].open – g_scalerMin[0]) * g_scalerScale[0]); input_data[i][1] = (float)((charges[i].excessive – g_scalerMin[1]) * g_scalerScale[1]); // … and so forth for low, shut, quantity … } // 3. Run prediction vectorf output_data(1); if(!OnnxRun(g_modelHandle, 0, input_data, output_data)) { Print(“OnnxRun failed!”); return; } // 4. Interpret consequence double probability_of_up = output_data[0]; // Now… what to do with this? ProcessSignal(probability_of_up); }
Half 3: The “Secret Sauce” – My Confluence Filter
That is what separates a “toy” from an expert instrument. I don’t commerce if probability_of_up > 0.5 . That is a rookie mistake.
As a substitute, I take advantage of the mannequin’s output as my major sign, which should then be confirmed by my confluence filter. This filter, impressed by my different EAs, is designed to reply one query: “Is that this a secure and logical time to commerce?”
Earlier than my new EA locations any commerce, it checks all of this:
Unfold Verify: Is the present unfold under my InpMaxSpreadPips ? If not, no commerce. Threshold Verify: Is the likelihood sign sturdy sufficient? (e.g., > 0.55 or < 0.45, primarily based on InpMinPredictionDiff ). Multi-Timeframe EMA: Does the ML sign align with the EMA development on the present, earlier, AND subsequent timeframes? RSI Affirmation: Is RSI above 55 for a purchase or under 45 for a promote? MACD Affirmation: Is the MACD line on the proper aspect of the sign line? Volatility Filter: Is the market transferring? We verify if ATR is inside a minimal and most pip vary. Pattern Energy: Is the ADX worth above 20, confirming a development is even current?
Provided that the ML sign is powerful AND the market context is logical does the commerce get positioned.
