Candlestick Patterns
Stick Sandwich
A black candle, a white candle that rallies, then a second black candle that closes right back where the first one closed. Build the sandwich, then see exactly how tight that close-to-close match really is.
Build the sandwich, then read the match
Seven candle cards sit in the tray, drag three of them into the bread, filling, and bread slots below. On touch, tap a card then tap a slot. Color rules apply immediately: the outer two have to be black, down candles, the middle one has to be white and close above both of them. Once color rules pass, the precision readout compares the two outer closes and the tolerance slider decides how close is close enough.
Fill all three slots to run the check.
How it works
- The outer two candles have to be black. Both close lower than they open. If either one is white, the badge fails immediately, no tolerance setting can fix a color rule violation.
- The middle candle has to be white and actually rally. Its close needs to sit above both outer candles' closes, that's the "failed rally" the sandwich shape represents, buyers pushed price up for one bar and then lost it.
- The two outer closes don't need to be identical, just close. Real charts rarely produce two candles that close at the exact same price. The tolerance slider sets how much difference still counts as a match, expressed as a percent of price so it scales with whatever the stock is trading at.
- Tightening the tolerance filters out near-misses. At 0.05% tolerance, only closes within a few cents of each other on a $50 stock pass. Loosen it toward 1% and looser "close enough" sandwiches start qualifying too.
- Order matters for the color check, not for building. Whatever card sits in slot one and slot three gets checked as a bread candle, whatever sits in slot two gets checked as the filling, regardless of which card you dragged from which tray position.
Where this breaks
Loosening the tolerance turns a specific pattern into a vague one
The entire idea behind stick sandwich is that price got rejected at almost exactly the same level twice. Widen the match tolerance too far and that specificity disappears, what's left is two down candles surrounding an up candle, a shape common enough that it stops carrying much information on its own. A trader who keeps loosening the tolerance slider until a marginal setup "counts" is really describing a different, weaker pattern while still calling it a stick sandwich. The precision readout on this page exists to make that trade-off visible instead of hidden inside a mental approximation.
