SwingBot Expert Advisor (EA) uses a unique approach for managing take profits of open positions. Instead of the traditional method of closing orders based on pips from the purchase price, this EA primarily focuses on the current profit. Such an approach can provide more control over trades, avoiding potential issues with broker's slippage that may limit profits.

Assessing the total number of active orders with the same magic number initiates this process. The magic number acts as an identifier attached to an order by an EA or a trader. The code initializes a variable - total_orders to zero, and then enumerates all open orders, incrementing the total_orders variable in case of a successful selection.

Following the total orders' calculation, the code initializes three variables: ProfittoMinimo, Profit, and StopLoss. ProfittoMinimo activates the take profit level (expressed in the ac...

Continuing the exploration into algorithms for problem-solving using reinforcement learning in a continuous action space, this piece shines the spotlight on Soft Actor-Critic (SAC). Presented almost simultaneously with TD3, SAC shares similarities with TD3 but also has notable differences, like its main goal to maximize the expected reward given the maximum entropy of the policy.

Behold, the SAC algorithm: both off-policy algorithms, SAC and TD3, exploit DDPG methods and they both use 2 Critics. However, unlike the other two methods, SAC employs a stochastic Actor policy, which enables the algorithm to explore various strategies and find optimal solutions, bearing in mind the maximum variety of actor actions.

When it comes to the stochasticity of the environment, it is understood that in S state when performing the A action, an R reward within [ R min, R max] is obtained with a Psa ...

In the realm of programming and technical analysis, the entry and exit rules lay the foundation for any successful trading strategy. On the one hand, long positions are entered based on the parameters of the Golden Cross strategy - three distinct conditions must be satisfied. Firstly, the value of the previous moving average should surpass the shorter-term moving average. Secondly, the value of the moving average two periods back ought to be lower than that of the shorter-term moving average. Lastly, the value of the moving average two periods prior must be lower than the previous short-term moving average. When these conditions align, it signals a Golden Cross and a long position is initiated.

On the other end of the spectrum are short positions, initiated based on the Dead Cross model. This scenario unfolds when the value of the previous moving average falls below the shorter-term...

Elastic net regression, a blend of ridge and lasso techniques, provides a potent solution to overfitting in linear models. This approach proves particularly pertinent in trading strategy development, where noise is often mistaken for patterns during training.

The process of Elastic net regression leverages the coordinate descent method of optimization, enabling a more efficient process. This method aligns with both lasso, which helps reduce training bias by repressing redundant predictors, and ridge regression, which minimizes coefficients to generalize the model. Two hyperparameters, alpha and lambda, govern the penalty term nature in the elastic net regression.

Alpha controls the type of regularization, whereby an alpha of zero reduces the penalty term to the l2-norm, and an alpha of 1 creates an l1-norm penalty function. A specified alpha between these two values allows for the...

In trading circles, the Engulfing Candlestick Pattern is generating considerable interest, particularly the hidden version. This pattern comes with an option to select either two or three bars break, opening up new strategic possibilities.

Consider a two bars break instance: Here, a bullish candle closes above the opening of a preceding bearish candle, all the while having at least one harami (a 'pregnant' candle) nested in the space between them. This forms a distinctive configuration, a strong indicator of deeper market shifts.

Meanwhile, the three bars break example expands on this. Here you have a bullish candle that again closes above its bearish predecessor's open. However, this time, you have the flexibility of having at least two intervening harami. This provides an enhanced dynamic, tapping into the shifting sentiment across an extended timeline.

Examining the topic of input parameters, particularly relating to AtrMultiplier and Period, it can be said that these play a critical role within coding and programming. The gist of it is the creation of six distinct lines. These lines are calculated using a formula that involves a multiple of the AtrMultiplier, the Atr value, and either the High or Low moving average.

As an example, calculating the upper line would involve doubling the AtrMultiplier, multiplying it by the Atr value and adding the result to the High Moving Average. Additional lines follow a similar logic, merely adjusting the multiplier and choice of moving average.

For programmers who are still green, a video tutorial has been created to expand on this task. This guide focuses on how to write an indicator in mql, which offers a new perspective on the application of input parameters within code. Over time, underst...
