Exploring the utilization of Long Short-Term Memory (LSTM) networks for price prediction in financial markets reveals promising strategies for handling time series data. LSTMs are beneficial due to their ability to remember long-term dependencies, dealing with one of the key challenges in traditional Recurrent Neural Networks (RNNs). This capacity is crucial for modeling sequences where context from much earlier inputs (such as past price movements) significantly influences current outputs.

The practical application involves normalizing price data on a daily rolling basis, recognizing the importance of adapting to intraday volatility and ensuring the model isn't biased by significant singular movements. This normalization strategy uses the highest and lowest prices within a day to scale price action between 0 and 1, refining how the model views price relationships.

In the latest discussion on improving data communication between Expert Advisors (EAs) and indicators in MetaTrader 5, we focus on refining the process of reading data from an indicator, a vital step for developing robust trading strategies. The new approach involves creating a clear channel for indicators to send meaningful data back to the EA, enhancing the interaction and integration of the two.

In our proposed method, a header file `Defines.mqh` is used to streamline the naming convention across the EA and the indicator, which helps in avoiding any discrepancies during the development process. This setup facilitates a smoother workflow by ensuring consistent references in both the EA and indicator codes.

The core of this system relies on the indicator having the capability to write data to a buffer, which the EA can then read from. By implementing this model, it ensures that the...

Understanding causal inference in the context of trading is an intricate yet vital aspect of developing robust predictive models. Recently, the focus has been on the use of propensity score matching (PSM), a technique predicated on the ability to estimate the average causal effect (ACE) even when data exhibits inherent biases due to variable treatments across a heterogeneous sample.

PSM addresses challenges particularly present in environments like Forex trading where market volatility significantly affects the data distribution in training sets. This method involves matching datasets with similar propensity scores, which are estimates of the probability of receiving a particular treatment given their baseline characteristics. By aligning units from both the treatment and control groups that share similar scores, PSM seeks to neutralize the effect of confounding variables, thus ensur...

Efficiency in coding has always been a critical aspect of software development. In a notable instance concerning linear regression calculations, a coder known as "mathemat" developed a streamlined formula for these calculations: `3*lwma - 2*sma`. This formula, utilizing lightweight moving average (LWMA) and simple moving average (SMA), both optimized for what is referred to as "loop less mode," offers an expedited approach to compute linear regression values accurately.

Although this method is efficient, it omits two crucial aspects found in the traditional linear regression calculations: the intercept and the slope of the regression line. Recognizing the importance of these components, an alternative approach has been proposed. This new method still adheres to the loop less mode for efficiency but incorporates both the intercept and the slope, ensuring a more comprehensive analysis....
