Guard and Escort

This Expert Advisor will be a good assistant for all Bill Williams fans! You do not need to analyze where to set a stop loss order for a new order and when to modify it. The EA detects an open order and chooses stop loss setting method. Then it trails the order either based on fractals or by alligator lines.


Initial stop loss setting methods:

  1. Main - below (above) one of the alligator lines, red or green.
  2. Fractal - based on the nearest formed fractal. Non-standard fractals are possible: 7- or 9-bar fractals and others.
  3. Emergency - at a specified distance from the price, when other methods are impossible.
    Pre-select the optimum value for the respective trading instrument!

Trailing options in the direct order from one mode to another. The opposite order is not possible: Then for BUY orders

  1. Emergency - till the first newly formed fractal below the current price, next move to the fractal mode.
  2. Fractal - as long as the price is below the alligator, stop loss is modified in accordance with new formed fractals.
  3. Main - once the price crosses the alligator lines ams bar closes above them, move to the main trailing mode. In this mode, stop loss is trailed parallel to the selected alligator line at a specified distance. The stop loss is modified as soon as the bar completely closes and is above the selected line, the bar body not touching it. If the completed bar touches the line, level is not modified, stop loss stays in its previous position preserving a valid distance from the price.

Note: You can jump directly from the emergency mode to the main one.
