Most breakout scanners look for price breakouts — a stock crossing above a resistance level. The problem? By the time price breaks out, the move is often 40-60% done. The smart money entered days earlier.
SpikeDesk detects breakouts before they happen by analyzing delivery percentage data. These six patterns capture the institutional footprint that appears 3-8 days before price visibly moves.
What it looks like: Delivery percentage is high (above the stock’s own average) but volume is normal or even below average. This has been happening for 3 or more days.
What it means: Someone is quietly buying and holding shares without creating enough volume to attract attention. This is the classic institutional strategy — accumulate in small blocks over several days to avoid moving the price.
Why it works: High delivery with normal volume means the buyers are real (not day-traders) but patient. The price breakout comes when they finish building their position and start buying more aggressively, or when other market participants notice.
What it looks like: Volume and volatility dry up for 5-7 days (the squeeze), then suddenly volume explodes with high delivery (the spike).
What it means: The quiet period was the accumulation phase. Retail traders left because “nothing was happening.” Then a catalyst triggers the move and the accumulated position drives a sharp price change.
Why it works: Low-volume periods indicate that selling pressure has been absorbed. When buying pressure suddenly arrives (the spike), there are few sellers left to resist the move.
What it looks like: Delivery percentage rises for 3 or more consecutive days. Each day, a larger fraction of trades are being held overnight.
What it means: The buying is getting more aggressive day by day. Institutional buyers are increasing their position size as they gain confidence.
Why it works: Consecutive rising delivery is very hard to fake. It requires consistent real buying. If delivery rises for 3+ days, someone with significant capital is building a position.
What it looks like: 3 or more of the last 5 trading days show delivery percentage above the stock’s historical average.
What it means: Consistent buying pressure over the past week. Not a one-day spike that could be a block deal or ETF rebalance — but sustained, repeated high delivery.
Why it works: The “3 of 5” filter eliminates random noise while catching genuine accumulation. A stock does not randomly have high delivery 60% of the time — something structural is happening.
What it looks like: Delivery percentage is rising but volume is flat or falling. Fewer people are trading, but those who trade are keeping shares.
What it means: Quality over quantity. The speculative traders have left, and the remaining activity is almost entirely institutional buying.
Why it works: This divergence is the purest accumulation signal because it explicitly separates real demand (delivery) from noise (volume).
What it looks like: Today’s delivery percentage is significantly above the stock’s own historical average — not just high in absolute terms but high relative to its own norm.
What it means: Something unusual happened today. Could be a block deal, an institutional entry, or a structural shift in the stock’s trading pattern.
Caution: This is the weakest pattern when seen alone. A single-day delivery spike has many possible explanations. Always look for it in combination with other patterns.
Each pattern contributes 2 points to the stock’s breakout score (max 12). SpikeDesk ranks stocks by this score and highlights those with multiple active patterns.
Breakout patterns are the first signal, not the only one. The highest-probability trades combine:
