Simulated Annealing (SA) algorithm's conventional version was discussed in the first part. This discussion revolved around three main concepts - randomness, acceptance of worse decisions, and reduction of the probabilities of accepting worse decisions. Think of a de-heated metal gradually cooling, causing shifts in its structure. Similarly, the Simulated Annealing algorithm starts from a high temperature and lessens the temperature incrementally aiming for the optimal solution. The algorithm's significant parameters, such as the initial temperature and the cooling ratio, can greatly influence its efficiency.

Some shortcomings of the system were examined as well. It was observed that this algorithm tended to get stuck at local extrema, which can be overcome by using an appropriate distribution of the random variable. Likewise, improving the convergence speed and efficiency of the algo...

A newly designed script offers its functionality to technocrats dealing with financial data, particularly those focusing on candle analysis. This script serves to perform several tasks with high accuracy and ease, hence simplifying decision-making in trading.

The script's primary function is data retrieval - it gathers vital information about the open, close, high, and low prices of candles pertaining to the attached financial instrument. Post retrieval, the script moves to categorize each candle as bullish, bearish, or neutral, founded on the direct comparison between its respective closing and opening prices.

A unique feature of this program is its ability to calculate the amplitude (the high-low difference) of every candle. Further, it comprehensively computes the average amplitude for both bearish and bullish candles, a crucial utility for making strategic, informed decisions.

In an attempt to increase efficiency in detecting new bars within a code, focus is shifted away from using time, and instead utilising the count of bars. This method is not only lighter, but also operates at a faster pace than its time counterpart.

Variables are declared using integer data type to contain the bar counts. Upon initialization, the bars count is assigned to the "BarsTotal_OnInt". The function iBars() is utilised to allocate the bars count for the "BarsTotal_OnTick" variable during live chart operations. It is important to note that this variable undergoes updates on every tick.

The accuracy of the code can be validated via the use of comments and alerts. Always strive to maintain a clean and concise programming culture, fostering a comprehensive understanding of operations. Leveraging the use of bar counts positively impacts output speed and greatly enhances overall c...

In the data-driven era, the Principal Component Analysis (PCA) stands as an indispensable tool for dimensionality reduction in large data sets. This process discards 'non-principal' components, essentially refining the data to its most significant vectors.

The key to a well-performed PCA lies in identifying those principal components, which can potentially be achieved through methods like the Eigen vectors & values, Singular Value Decomposition (SVD), and the Power Iteration. Like finding a diamond in the rough, PCA pinpoints the matrix vector that embodies the entire matrix's principal components.

PCA's ability to reduce the computation cost enhances efficiency when comparing data points in forecasting and diminishes computation time during model training. In a world where IT resources are precious, PCA can also help mitigate the 'curse of dimensionality,' minimizing storage spac...

A new cryptocurrency Expert Advisor (EA) has been developed, aimed at facilitating ETH/USD trading transactions. This application was birthed in response to challenges faced with timing and schedules in the flurry of day to day activities. Decentralizing the process, the EA is deployed on a Virtual Private Server (VPS), ensuring round-the-clock response to trading signals and entries.

The EA embraces a relatively straightforward strategy. It identifies the trend after touching the Bollinger Band (200), from which a trade is enacted on the 55 WMA breakout. Trailing is executed using the Bollinger Band, providing critical support for large-scale profits. Recommended for a 5-minute trade chart, the EA implements an extensive TP/SL ratio of 30/1 and trailing.

The complex market patterns encountered by programmers can be categorized into two distinct trends - horizontal and non-horizontal. To explain this concept in detail, let's consider the Janus factor, a theory that succinctly encapsulates the dual nature of these market trends.

Per the Janus theory, the market intricacies are driven by price oscillations and proportional trader responses, a mechanism akin to a feedback system. In trending markets, gained confidence motivates traders to augment their profits, leading to price escalation. Conversely, an atmosphere of uncertainty incites fear, encouraging traders to sell to curb potential losses.

An instrumental component of this feedback-based approach is the analysis of symbol performance in varied market conditions. The analysis evidences that traders usually favor high-performing stocks in an uptrend, while targeting under-performin...

In a recent release, a four-step process is outlined for developers to count "X" times and then pass in their code. The first two steps involve establishing a variable to set the count limit and recording the counted limit. The process continues with comparison of the counter and count limit, triggering the passage of a designated code block when equal. It concludes with resetting the counter to avoid an infinite count.

Another technique integrating wait times is also brought to light. This method alternates between passing and waiting intervals in the code. Counter and waiter variables are initially set, leading to pass or wait activities dictated by the count and wait limits. The final step is resetting both counter and waiter to maintain the function’s continuity. Users can implement filtering conditions to the counter and waiter blocks as per their requirements.

Fellow developers and technologists, here's an illuminating breakthrough into the process of restoring a historical position from trading deals. A position essentially, is a result of an executed trading order. Whereas obtaining open positions are straightforward, the complexity lies in retrieving already closed positions due to the absence of conventional functions to handle that. Yet, there's a workaround - complementing the unique ID assigned to each position.

This ID is what gets registered in deals affecting the position, such as opening, modification, or closure. By assembling a list of deals, links to positions associated with certain deals can be discovered. This way, the entry and exit deals for a position can be identified along with other key elements like time, and lot among others.

Building on that foundation, a loop can be used to generate lists of historical deals. Fo...

Latest developments in multi-symbol, multi-period indicators have uncovered a more streamlined way to process and display data. Drawing styles can now indicate whether a buffer is colour or not, providing a unique perspective to IT professionals examining the data. The capability to determine the source array for the class buffer, expedites the data copying process.

New indicator object creations now allow for an immediate setting of Digits and the initial "empty value" of data and colour buffer. Additionally, indicator levels and values can be set at creation. This feature simplifies buffer colour assignments and indicator properties.

However, the most significant development lies in the ability of multi-period indicators to use multiple arrays per plot buffer. This reduces the need to remember narrower specifics, such as the array assigned to the indicator buffer or indirect ind...

Evolution Strategies algorithms are optimization methods that mimic natural selection. Used primarily in machine learning and AI, they have been adapted since their emergence in the 1960s, subsequently becoming critical in solving complex optimization problems. By utilizing real vectors to represent solutions and various algorithmic operators, a more accurate solution space is achieved. Variants differentiate through their operators and population processing methods.

The (1+1)-ES variant, though less effective with complex problems, is a simple method that creates one child per parent, with the best solution becoming the future parent. This approach uses a random vector, modified per generations, until optimization.

The (μ,λ)-ES variant generates λ children from a population of μ parents, with the best replacing the parents. Created in 1965, this algorithm promotes a competition mod...
