In radio, parabolic antennas are used to radiate a narrow beam of radio waves for point-to-point communications in satellite dishes and microwave relay stations, and to locate aircraft, ships, and vehicles in radar sets. In optics, parabolic mirrors are used to gather light in reflecting telescopes and solar furnaces, and project a beam of light in flashlights, searchlights, stage spotlights, and car headlights. Since the principles of reflection are reversible, parabolic reflectors can also be used to collimate radiation from an isotropic source into a parallel beam.

Parabolic reflectors are used to collect energy from a distant source (for example sound waves or incoming star light). Conversely, a spherical wave generated by a point source placed in the focus is reflected into a plane wave propagating as a collimated beam along the axis. The parabolic reflector transforms an incoming plane wave travelling along the axis into a spherical wave converging toward the focus.

Its shape is part of a circular paraboloid, that is, the surface generated by a parabola revolving around its axis. Eventually the price will hit a dot (and the dots will move above the price) signaling a potential reversal to the downside.One of the world's largest solar parabolic dishes at the Ben-Gurion National Solar Energy Center in IsraelĪ parabolic (or paraboloid or paraboloidal) reflector (or dish or mirror) is a reflective surface used to collect or project energy such as light, sound, or radio waves. The SAR will continually rise though, acting as a trailing stop and, therefore, your stop loss order can rise with it. A stop-loss for long trades can be placed with the Parabolic SAR, currently at $73.60. To me this indicates a healthy trend which could likely continue. Average volume is higher due to the volume spike on May 9, but even without that volume is comparable to prior uptrend months. Despite the relatively high price, volume is also standing firm. The dominant trend is up, which could be confirmed with trendlines, but also by simply looking at the the amount of time the stock has spent trading above the Parabolic SAR dots. On May 13 the indicator moved below the price, after having been above for several days prior. Health Care REIT (NYSE: HCN) been in a strong uptrend, and a Parabolic SAR buy signal indicates another wave higher may be starting. Then I'll look to other indicators, such as volume or chart/price patterns, to see if they confirm the signal as well.

In the four cases below, I am mainly looking to see if a dominant trend is in place. You'll then want to look at the stock from other technical angles to see if the buy signal is worth taking. Therefore, the Parabolic SAR just provides potential trades. While the indicator provides buy and sell signals, they should not be trusted blindly. When the dots move below the price bars it is time to get long, or get out of short positions. When dots move from below to above the price bars, it is time to get out of longs or get short.

The indicator is composed of a series of dots, either above or below the price. Short for Parabolic Stop-and-Reverse, this indicator provides both entries and exits.

While I generally like to trade with few indicators and very little on my charts, the Parabolic SAR is one indicator that can be quite valuable.
