This is a trend following mechanical trading system developed by J.W Wilder. The name was derived from the pattern formed by the stops. The system is a true reversal system, every STOP being a REVERSAL POINT (SAR), when the SAR is penetrated the position is reversed.
A directional antenna with a feedhorn or low noise block amplifier pointed at a reflecting dish.
A special type of mic that can be used to record sounds from great distances.
A concave or dish-shaped object; often refers to dish antennas. Parabolic dish antennas tend to provide the greatest gain and the narrowest beamwidth, making them ideal for point-to-point transmission over the longest distances.
Long distance links Narrow beamwidth, similar to dish, careful alignment required
The Parabolic is a time/price system for the automatic setting of stops. The stop is both a function of price and of time. The system allows a few days for market reaction after a trade is initiated after which stops begin to move in more rapid incremental daily amounts in the direction the trade was initiated. For example, when a long position is taken the stop will move up regardless of price direction. However, the distance that the stop moves up is determined by the favorable distance the price has moved. If the price fails to move favorably within a certain period of time, the stop reverses the position and begins a new time period.
