Confirm an ascending triangle only after the flat cap breaks

Editorial reading: treat an ascending triangle as a demand-versus-supply hypothesis that needs an existing uptrend, a multi-session flat cap, and a rising floor. The archive workflow frames the long only after breakout confirmation, a $0.50 buffer or a large green candle, and volume confirmation, so the first poke is not the trade.

  • An ascending triangle is a consolidation with a horizontal resistance line lasting three days or longer and a rising lower trendline.
  • The rising lower boundary is presented as evidence that buyers are gradually overpowering sellers during a multi-day range.
  • A long entry is framed only after price breaks above the upper resistance line, not while the triangle is still forming.
  • A $0.50 buffer above resistance, or a large green candle at the upper-right of the pattern, plus high volume with a tall green candle, is used to confirm demand after the breakout.

What the archive means by an ascending triangle

An ascending triangle is described as a consolidation with a horizontal resistance line lasting three days or longer and a rising lower trendline. The rising lower boundary is presented as evidence that buyers are gradually overpowering sellers during a multi-day range.

Editorial reading: swing traders should treat that structure as a demand-versus-supply hypothesis. The hypothesis is only in play when there is already an uptrend, a multi-session flat cap, and a rising floor. The first poke at the cap is not the long.

The 2017 15-minute example

The worked example uses a 15-day 15-minute candlestick chart of an uptrend that formed an ascending triangle from January 5 to 9, 2017. A long entry is framed only after price breaks above the upper resistance line, not while the triangle is still forming.

In that example, resistance at $47.50 plus the $0.50 buffer produced a $48 entry after the January 10 breakout. Initial and trailing risk in the example is specified as $2.00 per share.

Breakout confirmation and volume confirmation

A $0.50 buffer above resistance, or a large green candle at the upper-right of the pattern, is used as a filter against false breakouts. High volume together with a tall green candle is listed as additional confirmation that demand is overpowering supply after the breakout.

Editorial reading: those steps make the long a falsifiable hypothesis. If the cap never breaks, if the $0.50 buffer is not cleared, or if volume confirmation is absent, the long is not framed.
