The simple ABC correction is a measured move down chart pattern nested inside a measured move up. If measured moves are unfamiliar, then click the associated link for more information. My book, Encyclopedia of Chart Patterns , pictured on the left, has a complete discussion of measured moves.

A Simple ABC Correction

Simple ABC Correction Identification Guidelines

NestedThe simple ABC correction is a measured move down chart pattern nested inside a measured move up.
ChartSee the above chart. Point D must be below point C, meaning that the measured move down (MMD: EABC) must not correct too far. MMDs that correct too far fail more often.
Corrective phaseThe corrective phase of the large MMU is an MMD, like the ABC pattern shown in the above chart. Only one MMD should be present with two straight-line runs, EA and BC. Discard patterns with pronounced turning points within those two down legs.
PointsWithin the MMD, points A, B, and C are below E. Be especially careful that B not be above E. Point C starts a major price up swing.


Simple ABC Correction Trading Tips

Reference the figure on the right.

Trading TacticExplanationShows a Simple ABC correction
TrendlineDraw a trendline from E to B and extend it downward. When price closes above the trendline, buy.
SwingersFor aggressive traders, draw a trendline down from B along the tops and buy when price closes above it. A close above the intraday high at A (blue trendline) also works as a buy signal.
BuyFor conservative investors, a close above B or even E is the buy signal.
ReverseBe prepared for price to reverse at the price of E – 36% do and prices drop, confirming a double top.
