FEATURES
- HMM uses the famous Hidden Markov Model to predict the price trend.
- It uses the algorithms of Baum-Welch and Viterbi to train the model and predict price trend.
- This implementation of Hidden Markov Models is a self-adjusting online learning algorithm that processes up to 160 bars from the latest data to readjust its parameters at the arrival of every new bar.
- It trades ANY Forex pair, ANY metal symbol. We recommend major ones: combinations of USD,GBP,JPY,EUR,AUD,CAD,XAU.

THE TRADER’S ENVIRONMENT: A CRITICAL FACTOR IN BACKTESTING
Every trader operates within a unique environment, defined by three key components:
1. Broker : Prices, spreads, leverage, fees, and commissions vary across brokers, impacting trading outcomes.
2. Network : Local internet connection speeds influence execution speeds, affecting entry and exit prices.
3. Computer : Processing power and internet connection speed combine to determine delays and slippage.
These environmental differences mean that two traders using the same:
- Expert Advisor (EA)
- Input set file
- Symbol
- Time frame
- Dates
will never achieve identical backtest results. While results may be similar, variations in environment ensure that outcomes will always differ. Therefore, running optimization of the input parameters before you start trading in your environment is critical. This step helps ensure that your trading strategy is tailored to your unique environment, maximizing its potential for success.
Risk Warning
Before purchasing this (or any) EA, be aware of the risks involved.Past performance is not a guarantee of future profitability (EA could also incur losses).
Backtests shown (e.g., in screenshots) are optimized for the training data, and the performance cannot be directly applied to live trading.
There is a probability (although small) when using any EA that you may lose money in all your trades.
Hence, risk the amount of money you are comfortable losing.
