How delivery percentage is analysed
Each stock's delivery % compared with its own recent normal, as a z-score.
NSE's daily security-wise delivery file reports, for every stock, how much of the traded quantity was deliverable. Delivery levels differ enormously between stocks, so Flash Finance never applies a flat "above 50% is high" rule. Each stock is compared with its own recent normal: the average over the previous 40 calendar days (about 20-28 sessions), with at least 10 sessions of history required.
z = (today's delivery % − the stock's normal) ÷ the stock's standard deviation
If the stock's delivery barely varies (σ below 1 point): z = (today ÷ normal − 1) × 4
| Label | Rule | |
|---|---|---|
| Accumulation | Price up ≥ 1% and z ≥ +1 | |
| Distribution | Price down ≥ 1% and z ≥ +1 | |
| Speculative move | Price up ≥ 2% and z ≤ −1 | |
| Quiet accumulation | Price move under 1% and z ≥ +1 | |
| Weak hands | Price down ≥ 2% and z ≤ −1 | |
Stocks with under ₹1 crore of turnover that day are left out: below that, a large percentage change is a handful of trades. The labels name a pattern in the data. They do not claim to know who traded or why, because every delivered share was also sold by someone.
