Darvas Box Breakout
Nicolas Darvas's box theory treats a stock's price as stacking boxes on the way up, each one confirmed by a real 3-bar rule, and each breakout above a box top becomes the floor of the next one.
Watch the boxes stack, then race the breakout
A generated session plays out bar by bar. Every box ceiling and floor on the chart gets confirmed live by the same 3-bar rule Darvas used by hand. When a bar's real close clears the current box top, click Breakout as fast as you can. Click on a wick that closes back inside the box and it counts against you.
Building the first box…
How it works
- A box ceiling confirms after 3 consecutive bars fail to make a new high. The tool tracks the running peak. Once a bar sets a new high, if the next three bars in a row each fail to exceed it, that peak becomes the confirmed box top.
- A box floor confirms the same way, in reverse, starting from that peak. The tool tracks the running low from the peak forward. Once three bars in a row fail to make a new low, that low becomes the confirmed box bottom.
- Boxes stack as price grinds higher. Once a box breaks out (a real close above its top), the tool starts hunting for the next ceiling starting right at the breakout bar, so the breakout zone becomes the floor-forming area for the box above it.
- A clean breakout is a close above the box top, not just a touch. A bar that wicks above the top and closes back inside is a false breakout and scores against you if you click it.
- Volume confirmation is what separates a real breakout from a weak one in this tool's scoring. Each breakout bar carries a real simulated volume reading. The tool tracks separately how many of your clean catches also came with volume confirmed above its trailing average, since a breakout on light volume is a weaker signal even when the close technically clears the box.
Where this breaks
Box theory needs a real trend to stack on
Darvas built this method during a strong sustained runup, and it works best in that kind of tape. In a choppy, rotational market the peaks and lows never settle long enough for a clean 3-bar confirmation, boxes get confirmed late or not at all, and the breakouts that do print fail at a high rate because there was never a real trend underneath them to begin with. The 3-bar rule does not know the difference between a stock in a genuine uptrend and one drifting sideways, it just counts bars, so this tool will keep drawing boxes in both conditions even though only one of them gives the breakout much of a chance.
