"Parabolic arc" is a reversal pattern and has a very predictable outcome. Although they are predictable, they are relatively difficult to trade since the market sentiment is bullish and may be relatively tough to point reversals to trade. Most "Parabolic arc" patterns have a significant correction of 62% from the top.
Trade: After a parabolic base, prices move up vertically and eventually the acceleration comes to a stop and then reverses. Prices start showing lower-lows and may attempt to regain the top again. Enter a "short" trade at the second failed attempt to test the peak or at the trend line breakdown connecting the major swing lows.
Target : Measure the distance of the rise from base to the top. Most parabolic arc result in 62% retracement.
Stop: Protect the trade by placing few ticks above the high point of the Parabolic Arc.
