more...Piecewise linear representation of time series is a method of approximating a time series using linear functions over small intervals. In this article, we will discuss the algorithm of Bidirectional Piecewise Linear Representation of time series (BPLR), which was presented in the paper "Bidirectional piecewise linear representation of time series with application to collective anomaly detection". This method was proposed to solve problems related to finding anomalies in time series.

In this article, we will outline the implementation process of a calendar-based breakout strategy in MQL5. We'll cover everything from creating a class to interpret and store calendar data, developing realistic backtests using this data, and finally, implementing execution code for live trading.

Next, we'll go one step further and transform the Moving Average from the conventional line shape into a candle-style indication. In addition, this practical method will open up new avenues for developing trading tools that are specifically suited to your requirements.

It's not uncommon to come across code that appears correct at first glance but ends up producing completely unexpected results in certain situations. This type of issue is often directly related to how the factorizations are implemented. Getting a piece of code to deliver consistent results may seem like a trivial task. However, without the proper knowledge (as demonstrated in that article), the likelihood of catastrophic failures increases as more and more poorly implemented factorizations are introduced into the code.
more...The proposed Object Cluster Module plays a crucial role in enabling the model to achieve a deeper, more holistic understanding of both linguistic and visual information.
more...In this article, we will develop an MQL5 Expert Advisor designed to identify liquidity sweeps as they unfold. The EA begins by analyzing candles that break below or above previous swing points, then close back within the range, indicators of potential liquidity absorption. It incorporates optional filters, such as candlestick color changes or moving average confirmations, to ensure the signals align with your market bias. When a valid pattern is detected, the EA visually marks it on the chart with arrows or labels and generates an alert.

This is possible thanks to DroiTong, a compatible tool available in the Huawei AppGallery that enables you to run Android apps on HarmonyOS NEXT. This guide will walk you through the straightforward process of getting these essential applications up and running on your device.
more...In our last article we introduced 5 signal patterns from the pairing of the Gator and the Accumulation/Distribution oscillators, in this article we consider the final 5 of this set of 10. We have been looking at 10 signal patterns for each indicator pairing, and we will be maintaining this format. From the testing in the last article which was done on the pair GBP JPY on the 30-minute timeframe, our results indicated that the patterns 0, 3, and 4 struggled to forward walk, however before we can choose what to improve with supervised learning, let's complete examining and testing of patterns 5 to 9.
Demo trading taught me more about timing and discipline than any book ever could. Both basic knowledge and demo practice are essential - and combining theory with real‑market practice is a cornerstone of my own journey
