Parabolic Trend

An advance or decline that steepens, rising or falling at an increasing slope.

Teaching sketch. It shows the shape, not a live quote and not a trade signal.

Definition

A parabolic trend curves. Each swing is steeper than the last, so a straight trendline no longer contains it. The move accelerates. Parabolic rises are associated with blow-off buying. Parabolic declines are associated with liquidation. The curve cannot continue. The hard part is when it stops.

How to identify it

A trendline you have to redraw steeper, pullbacks that get shorter, and price pulling away from a long moving average. Parabolic SAR was designed to trail this kind of acceleration. The shape is the price, not the indicator.

Bullish reading

While the curve holds, momentum is with the buyers, and fading it is how accounts get hurt. Trailing under the latest higher low, knowing the low is close because the swings are steep, is the trend-following approach.

Bearish reading

The end of a parabolic rise is often a sharp give-back, because the late buyers have no base under them. A break of the latest steep trendline plus a break of the last higher low is the evidence. The first red candle is not.

Common mistakes

Shorting a parabola only because it is vertical. Vertical can become more vertical. Wait for structure to break, or do not take the trade.

Limitations

Parabolic moves overshoot every tool that assumes a constant slope. Measured targets from the base of the curve are guesses once the curve is the whole chart.

This note explains the term. A sketch shows the shape of the idea. Neither is a recommendation, a signal, or a comment on any security. Indicator settings and exchange conventions differ. Check the live chart and the contract specification before you use a number.
