Conversely, points located above illustrates the price that bears are in control and that the momentum is likely to remain downward.
As we know that many kinds of indicators in forex trading, which draw from the parabolic SAR is located on the ease of use (easily seen) from the above brief description by no means a simple look ..
In addition, this indicator has another feature that is in the show during the reversal (end) of a trend.
In the picture below shows how parabolic SAR to help give the trend reversal signal. When a new point appears above the mean trend of next is bearish (down), to be sure wait until form 3 points above.
And in the next example, a new point appears below the price, meaning the next trend is bullish (rising).
Other uses of the SAR, is to show us, when should we have to get out of our current trade.
In the picture above, you bet If a sales position, then when the parabolic SAR led to three new point below, we recommend that you immediately close to the position and recorded a gain, because there most likely will turn bullish trend, so that your profit potential is lost.
So if there are 3 new point of sale under the = trend is over, get ready for the trend to buy / bullish.
Currently there are 3 points above = new purchasing trend ends, preparing sales trends / bearish.
