Volume Surge & Operator Stage Detection
Observable Volume Surges (>1.5x 20d), Price Expansion & CMF Accumulation
Methodology Overview
The Volume Surge & Stage Detection engine replaces speculative rumors and superstitious "operator" naming with observable, mathematically verifiable market microstructure metrics. It tracks volume surges exceeding 1.5x the 20-day baseline, positive price expansion, and positive 20-period Chaikin Money Flow (CMF > 0) to detect institutional footprint accumulation.
Core Empirical Hypothesis
Large institutional accumulation leaves an undeniable physical footprint in the order book: volume multiples jump over 1.5x prior averages, closing prices print in the upper half of the daily candle (CMF > 0), and price volatility expands. Entering at Stage 1 (Stealth Accumulation) or early Stage 2 (Initial Uplifting) yields high risk-to-reward ratios before general retail participation.

First-Principles Formulations
\text{MFM} = \frac{(C - L) - (H - C)}{H - L}, \quad \text{MFV} = \text{MFM} \times V, \quad \text{CMF}_{20} = \frac{\sum_{i=1}^{20} \text{MFV}_i}{\sum_{i=1}^{20} V_i}Measures whether volume is flowing into closes near daily highs (+1.0 max) or near daily lows (-1.0 max). CMF > +0.05 indicates systematic accumulation.
R_{\text{vol}} = \frac{V_t}{\text{SMA}_{20}(V)} > 1.50Identifies abnormal session turnover that exceeds normal baseline by 50% or more.
\text{Stage} = \begin{cases} \text{Stage 1: Stealth Accumulation} & R_{\text{vol}} \ge 1.5, \, -1\% \le \Delta P \le +3\%, \, \text{CMF} > 0.05 \\ \text{Stage 2: Initial Uplifting} & R_{\text{vol}} \ge 2.0, \, \Delta P > +3\%, \, \text{CMF} > 0.15 \\ \text{Stage 3: Dump / Distribution Risk} & \text{Near 52W High}, \, R_{\text{vol}} \ge 2.5, \, \Delta P \le 0\%, \, \text{CMF} < 0.0 \end{cases}Categorizes price-volume behaviors objectively without imputing unverifiable intent to specific market individuals.
Operational Strategy Rules
Volume Ratio >= 1.5x AND CMF_20 > +0.05 AND Price Expansion > 0Confirms high volume accumulation with closing price in upper range of candle.
Turnover >= 1.0M BDT AND Value Turnover > 20d AvgGuarantees order execution capability without excessive market impact.
CMF drops below -0.05 OR Price breaks 5-day lowExits immediately if volume shifts toward distribution.
Holding Duration >= 25 Trading Days OR Gain >= +18%Takes profits as initial markup cycle reaches maturity.
Volume surges cannot occur while stocks are pinned at floor prices with zero bids. Artificially suppressed volumes distort CMF moving averages upon initial unfreezing.
Small-cap speculative favorites often experience sudden circuit breaker halts. Volume surge entries must account for locked exit gates.
Holding horizon of 20–30 days balances turnover against the 0.40% round-trip commission constraint. Trading shorter intraday surges is unviable on DSE.
Volume surge setups often cluster within specific speculative sectors on the same day; strict single-sector portfolio caps must be enforced.
