How the Scoring Works (0–5 points)
Each condition adds 1 point:
✅ 8 EMA above 20 EMA (trend direction)
✅ OI Proxy confirms direction (Volume + Price interpretation)
✅ Sector index trading above its 20 EMA
✅ RSI not in extreme zone (not overbought for CE / not oversold for PE)
✅ Volume spike ≥ 1.5× the 20-bar average
Score ≥ 4 → High conviction signal → BUY CE or BUY PE label appears on chart
Score 3 → Weak setup — wait for confirmation
Score < 3 → No trade
Dashboard Shows (top-right panel)

Always verify news and catalyst on NSE website or Screener.in before entering

Built-in Alerts
🟢 Strong BUY CE — EMA cross + OI + Sector all aligned (score ≥ 4)
🔴 Strong BUY PE — EMA cross + OI + Sector all aligned (score ≥ 4)
📊 EMA Bull Cross — 8 EMA crossed above 20 EMA
📊 EMA Bear Cross — 8 EMA crossed below 20 EMA
📈 Volume Spike in Bull Trend
Note on OI Data
For real open interest data, switch to the futures chart (e.g. NSE:RELIANCE1!). On equity charts this script uses Volume + Price direction as an OI proxy, which closely mirrors standard OI interpretation (Long Buildup, Short Buildup, Short Covering, Long Unwinding).
Settings
All parameters are adjustable — EMA lengths, ATR multiplier, Risk:Reward ratio, OI proxy sensitivity, and sector index. Tooltips explain each input.
