Substantive update: October 3, 2026. Removed unfinished drafting placeholders and replaced claims of confirmed outcomes with a sourced explanation, an illustrative example and execution-risk caveats.
A triple bottom is a technical-analysis label for three separated lows around a similar price area after a decline. In the conventional interpretation, a move above the intervening highs completes the pattern. It does not establish that the next trade will be profitable.
What the pattern describes
StockCharts’ ChartSchool explanation describes an existing downtrend, three reasonably comparable lows, and a resistance break. The lows need not be identical. Resistance is associated with the highest intervening rebound. Some analysts also look for increased volume on the breakout.
Without that break, three lows can simply describe a trading range. Similar-looking formations can receive different labels as prices develop. A double bottom has two lows; a triple bottom has three. The extra low is not proof of greater predictive reliability. These descriptions concern ordinary price charts, not similarly named point-and-figure signals.
A hypothetical example, not a trade recommendation
Imagine a fictional share declining from $70, reaching lows near $50 three times, and rebounding no higher than $56 between them. A subsequent move above $56 would meet the breakout element of this simplified example.
The conventional measured-move calculation adds the pattern’s $6 height to $56, giving $62. That number is a charting convention, not a forecast or independently tested expected return. We have not backtested this example or assigned it a success probability.
If someone assumes an entry at $57 and an exit at $49, the planned difference is $8 per share. For 25 shares, that is $200 before costs. Actual loss can exceed $200: an assumed exit price is not a guaranteed execution price.
Why a visually convincing setup can fail
- False breakout: price can move above the selected resistance level and then fall back.
- Subjective boundaries: changing the time frame or choosing different turning points changes the picture.
- Hindsight: a clean pattern identified after the outcome may have been ambiguous at the time.
- Execution and costs: spreads, fees, gaps and unavailable liquidity can make an achievable result differ from the chart.
Stop orders are not loss guarantees
FINRA’s stop-order guidance explains that a triggered stop order becomes a market order and may execute far from its stop price. A stop-limit order controls the acceptable price but may not execute at all. Broker rules and the instrument being traded also matter.
Position-sizing arithmetic can express a planned risk budget; it cannot enforce a maximum loss when prices gap or orders do not fill as assumed. The InvestPips tools can help explore assumptions, but their output is not execution protection.
A better way to study it
Write down the pattern definition and entry/exit assumptions before observing subsequent prices. Record failed examples as well as successful ones, include realistic costs, and separate exploratory results from any later out-of-sample test. A memorable chart is not evidence of a durable trading advantage.
