The Expert Advisor generates trading signals based on the FractalDivergence_Patterns indicator.

A buy signal is generated when the support level indicator registers, and a sell signal is generated when the resistance level is registered (see Figure 1, blue arrows – buy, red arrows – sell). The Expert Advisor does not require the presence of the specified indicator and at the same time can independently display the support and resistance levels.

The “Fractal divergence parameters” block”

• Color of bull pattern – color of support levels
• Color of bear pattern – color of resistance levels
• Is show data? – switch to display support/resistance levels
• Bars to calculate – the number of bars where support/resistance levels are displayed

The “Order volume” block”

• Order volume – the volume of any order opened by the Expert Advisor
• Use StopLoss and TakeProfit? – switch for setting the Stop Loss (SL) and Take Profit (TP) levels)
• No – any order is opened with zero values of SL and TP
• Yes-the order is opened with the calculated SL and TP (see below)
• Shift for Stop Loss, pts. – the distance of the SL order from the lower limit of the support level (for the Buy order) or from the upper limit of the resistance level (for the Sell order)
• TakeProfit to StopLoss ratio – ratio of TP size to SL size

[spoiler title=”Read More…”]

• No – any order is opened with zero values of SL and TP
• Yes-the order is opened with the calculated SL and TP (see below)

The “Tactics parameters” block”

• Tactics type-switch for the ADVISER’s tactics option
• Locks free – when the Buy trading signal is received, all existing Sell orders opened by the Expert Advisor are forcibly closed, and, conversely, when the Sell trading signal is received, all Buy orders are closed.
• With locks-independent opening of Buy and Sell orders, which does not lead to the forced closing of a particular order
• Max orders in series – the maximum number of orders in one direction
• Add orders type-specifies the order opening option if ” Max. orders in the” more than 1 ” series
• Averaging – a Buy order can only be opened below all other Buy orders, and a Sell order can only be opened above all existing Sell orders
• Refilling – a Buy order can only be opened above all other Buy orders, and a Sell order can only be opened below all existing Sell orders
• Any-order can be opened either above (but not between two orders), or below all existing orders of the same type
• Shift for next order, pts. – the number of points for which the new order should be further than the maximum or minimum price
• Close buy by profit, pts. – the number of profit points of Buy orders (if there are 2 or more), at which they will all be closed
• Close sell by profit, pts. – the same, but for Sell
• Close all by profit, pts. – if there are counter orders and their volumes are not equal, then when they reach the total profit in points, all the Expert’s orders are closed

• Locks free – when the Buy trading signal is received, all existing Sell orders opened by the Expert Advisor are forcibly closed, and, conversely, when the Sell trading signal is received, all Buy orders are closed.
• With locks-independent opening of Buy and Sell orders, which does not lead to the forced closing of a particular order

• Averaging – a Buy order can only be opened below all other Buy orders, and a Sell order can only be opened above all existing Sell orders
• Refilling – a Buy order can only be opened above all other Buy orders, and a Sell order can only be opened below all existing Sell orders
• Any-order can be opened either above (but not between two orders), or below all existing orders of the same type

The “Other parameters” block”

• Points ratio – the value by which all the parameters of the Expert Advisor are multiplied, expressed in points
• Slippage – the maximum deviation from the requested price in points, when opening and closing market orders
• Order open sound – the name of the sound file that is played when the market order is opened
• Experts orders ID – the ID used by the Expert Advisor to mark the orders it opens to distinguish them from orders opened by other Expert Advisors

The Expert Advisor can work in the classic flip strategy mode. To do this, specify the “Type of tactics” – “No locks”, and ” Max. orders in the series ” – 1. An example of such a strategy is shown in Figure 2.

It is also possible to independently manage each type of order (“Tactics type” – “With locks”). Moreover, for each of the directions, you can create a whole series of orders (“Max. orders in the series” more than 1). In this case, each subsequent order is opened only if a trading signal appears and only if the distance from the highest-priced or lowest-priced order of the same type is greater than or equal to the value “Indent for the next order, pp”. For such strategies, it is more convenient to use the absence of SL and TP for orders. In this case, the series will be closed when the total profit is reached.
