What the ratio tells you
Think of every period as a tug-of-war. Buyers pull price up, sellers pull it down. The candle is the scoreboard, and the shape tells you who won and how contested it was.
- Long body, short wicks. One side dominated. Price moved decisively from open to close and was never seriously pushed back. This is conviction.
- Short body, long wicks on both ends. Both sides had a turn and neither kept it. Price travelled a long way and ended roughly where it started. This is indecision, and it is more common than beginners expect.
- Long wick on one side only. One side made a serious attempt and had it completely rejected. That rejection is often the most useful single piece of information on the chart.
The long lower wick is the one to learn first
Look at the fourth candle again. Price was driven down a long way — nearly nine points below where it opened — and then bought all the way back to close essentially unchanged. Whatever selling happened there, buyers absorbed it. That is a rejection of lower prices, and it is the mechanism behind most of the reversal patterns in Part 2.
The mirror image is a long upper wick: price was pushed up and sold back down. Buyers had their turn and lost it.
Context decides whether rejection matters
Here is the catch, and it is the single most important idea in this course: a long wick only means something relative to what came before it.
A long lower wick after a sustained decline is genuinely interesting — it is the first evidence that sellers are losing. The exact same long lower wick in the middle of a choppy range is just noise; price tests both directions constantly in a range and nothing has been rejected in any meaningful sense.
This is why the same shape has two different names in the pattern books. A small body at the top with a long lower wick is a hammer after a decline, and a hanging man after a rise. Same geometry, opposite interpretation. Part 2 covers both.
How to check this yourself
Scroll through a chart and find the five candles with the longest lower wicks. For each one, note where it sits: after a fall, after a rise, or in the middle of nowhere. Then look at what happened next. You will find the ones after a fall behaved very differently from the ones in the chop — and you will have learned the central lesson without memorising a single pattern name.
