Substantial strides have been made in developing a market replay system, simulating a distinctive symbol with dynamic yet stable capabilities, increasing the breadth of potential scenarios that can be tested. The aim is to authentically parallel movements observed in a real market scenario.

However, the simulations created so far struggle to encompass the complete range of possibilities, often missing critical data points. The current model, based on the RANDOM WALK principle, proves to be insufficient due to its inability to completely mirror the span of actions within different market conditions. Merely relying on chance is not a viable solution.

A supervised form of RANDOM WALK, fusing abstract mathematical concepts and code has the potential for achieving accuracy while ensuring all specified points are reached. The upcoming discussion will delve into the simplistic core concep...

The ability to successfully conduct trading operations stems from effective utilization of MqlTradeRequest structure when creating a trading request. Specifics of each operation, trade volume request, and the trading instrument itself are among the elements affected by trade requests. Ensuring these factors are properly accommodated can significantly increase the proficiency of trading operations.

For instance, the interaction between the client terminal and trading server, engaged in order placement, is dictated by trade requests. The specification of actions forms the backbone of these requests, with the resulting operations being handled appropriately.

In addition, while filling in required fields of the structure, one can set a trade order to the server. These entries can range from the proposed volume of a trade deal, price, stop-limit order level, to even comments on an order...

Unveiling the functionalities of the Donchian Channel indicator, a comprehensive tool in market trading. Developed by Richard Donchian, it utilizes the highest high and lowest low from a stipulated number of periods to determine market volatility. Clear demarcation of high and low values exhibits the channel and aids in discerning price stability.

The indicator underscores four key buffers: Upper Donchian Channel (Buffer 0 - Green Line), Middle Donchian Channel (Buffer 1 - Blue Line), Lower Donchian Channel (Buffer 2 - Green Line), and MA Donchian Channel (Buffer 3 - Red Line). Each contributes to the overall authenticity of this dynamic trading instrument.

Breaking down the code, the high and low values from the set 'n' period are extracted initially, followed by an average to generate the Middle Line of the Channel. A moving average of the Middle Donchian Channel is then calculate...

Addressing a technical concern within the realm of developing a replay system, an issue appears regarding the use of current replay systems. They are ill-fitted for the exploration and practice of certain operation systems, an issue largely stemming from a lack of pre-analytical capabilities. The unavailability of these crucial bars leads to an inability in gaining reliable indicator information. Addressing this is the necessity to conduct careful and appropriate calculations considering the largest period needed for each indicator to generate useful data.

Furthermore, modifying the replay system necessitates an understanding of details regarding the chart period to be used in the replay, along with the minimum period required for useful information generation. These considerations determine efficiency when we apply them to create a market simulator. The difference between the replay...

In the realm of trading algorithms, a novel feature has been integrated into a specific indicator. This feature offers an input field dubbed 'multiplication factor'. Users are given the leverage of inputting any value of their preference to identify a custom hammer or inverted hammer.

For instance, when using a multiplication factor of 1.25, the algorithm is designed to search for a hammer wherein the shadow of the hammer is at least 1.25 times of the body. In contrast for the inverted hammer, the factor applies inversely.

The results are denoted by plotting a specified color input into the system, making the custom hammer or inverted hammer easy to distinguish. This update leads to improved efficiency and precision in recognizing trading patterns, providing an upper edge to strategists in their respective trading markets.

Proposing a new approach to handling the problem of large, unwieldy source code in the context of swapping or adding ONNX models. This involves utilizing object-oriented programming to streamline workflows and enhance the outcomes of trading strategies.

Three distinct classification models were trained on MetaQuotes-Demo server data, each with different counting techniques and averaging periods. Through the utilization of the base class, the models shared a uniform interface and were implemented with methods like PredictPrice or PredictClass as per the specific requirements.

Key functions were redefined for each model class to manage the sizes of the input and output tensors. Complementary Expert Advisors were created for the evaluation of every model's performance.

The final test combined the strengths of all models; the hard voting technique offered improved outcomes - profita...

Update on v1.01: Noteworthy modifications have been implemented which include the incorporation of a magic number, an overseer on the symbol which allows for multiple chart attachments within the same account, a time controller for trading, and an option for forceful closure of all trades once the end hour is reached.

The EA carries out the deployment of a grid consistent with pending limit orders in synchronization with the current price, the selling limit above and buying limit below, as well as the trading range, which is computed through the use of weekly highs and lows.

Subsequent to the execution of the orders, the EA administers them. The operational rule is that if the number of executed orders amounts to 2, a new limit is opened at the pen price. If the number of executed orders exceeds the total minus 2, the limit orders are reset to the range. For an exhaustive overview...

In the realm of technical analysis, candlestick patterns provide crucial insights. Specifically, the interplay between bullish and bearish candles can portray potential trading signals. Consider this scenario: A bearish candle is observed and is instantly succeeded by a bullish candle, where the bullish candle opens below the closing rate of the preceding bearish candle. In such cases, the graphic representation marks a bullish arrow.

Conversely, when a bullish candle is succeeded by a bearish one, and the bearish candle opens above the closing point of the bullish candle in the market, a bearish arrow is plotted on the chart. Such patters are critical in the interpretation of trading signals. They can help traders to predict the possible future behavior of market prices.

Remember, understanding these subtle clues of candlestick patterns can be the difference between profitable trad...

A fundamental aspect to consider in financial graph analysis pertains to 'candles'. A 'candle' without a corresponding 'wick' replaces the standard representation with an "x" via the Wingdings font. This technical aberration creates a unique subplot within the broader analytic framework, calling attention to specific data points for closer scrutiny. True to its name, the 'candlestick' graph, derived from ancient Japanese rice trade, is a sophisticated tool for recording price movements over discrete periods. The wick's length insinuates volatility within that period - a valuable cue for financial analysts. Consequently, the absence of a wick and the resulting 'x' sign serve as crucial indicators for seasoned traders and programmers in the domain.

Understanding changes in candlestick patterns can provide substantial insights for market trends. An event occurred where the most recent candlestick's body was entirely submerged within the preceding candle's wick. This kind of formation may convey crucial market dynamics, potentially signifying a trend reversal, depending on other supporting indicators. It's an unmissable chance to refine the trading strategy and adjust risk parameters to suit these new insights. Stay updated.
