CE-PE Crossover Strategy Guide

Overview

What this strategy does

Every morning, the ATM Call (CE) and Put (PE) options open at a certain premium. As the market moves, one premium rises while the other falls. This strategy watches the speed of that change — and enters only when one side has clearly taken control.

You are not predicting direction. You are confirming it after the market has already shown its hand — then joining it.

Setup

Before 9:15 AM — get ready

1

Open the Osprey tool

Go to CE-PE Crossover Calculator on TradeZen. Select NIFTY or BANKNIFTY. Choose the nearest weekly expiry from the dropdown.

2

Fetch the ATM strike

Tap Spot ↗ to auto-fill the ATM strike rounded to the nearest 50 (Nifty) or 100 (BankNifty). Or type the strike manually — the field rounds automatically on blur.

3

Fetch live CE and PE premiums

Tap Chain ↗ — the tool pulls ATM CE and PE prices directly from the live options chain. Tap → Set as Base to lock the 9:15 AM opening prices. These are your reference for the entire day.

4

Enable Auto Refresh

Tap the Auto Refresh button — it fetches current CE/PE from the chain every 30 seconds, updates the chart, and auto-sets the VWAP position. No manual tracking needed during the session.

Calculation

The % change formula

This is the only number you need to track. The tool calculates it live.

Formula

% Change = ((Current Premium − 9:15 Premium) ÷ 9:15 Premium) × 100

— CE opens at ₹120. Current CE = ₹141.
% Change = ((141 − 120) ÷ 120) × 100 = +17.5%

— PE opens at ₹115. Current PE = ₹108.
% Change = ((108 − 115) ÷ 115) × 100 = −6.1%

→ CE dominance = 17.5 − (−6.1) = +23.6% → CE setup fires ✓

Entry Rules

When to enter — the 15% dominance rule

Both conditions must be met simultaneously. The 15% spread filters out false moves — small crossovers on choppy days won't trigger a setup.

Bullish setup

CE Setup Active ▲

CE% − PE% > +15%
CE % change > 0
Spot above VWAP (confirm)
After 9:20 AM only

Bearish setup

PE Setup Active ▼

PE% − CE% > +15%
PE % change > 0
Spot below VWAP (confirm)
After 9:20 AM only

The 15% dominance gap — not just the winner's threshold — is what distinguishes a committed move from noise. At CE +11%, PE −2%, spread is 13%: the move hasn't committed. At CE +17%, PE −3%, spread is 20% — real money has taken a side.

Confirmation

The VWAP rule — never skip this

VWAP shows where the majority of today's volume has traded. The Osprey tool auto-detects VWAP position when you tap Spot ↗ or enable Auto Refresh.

Risk Management

Size your trade before you enter

Never enter without knowing your maximum loss in rupees. The Osprey tool shows this in the Risk Reference card. Use the calculator below to plan lot sizing.

One lot stop loss exceeds your risk limit. Consider paper trading until capital grows.

Capital is too small for even one lot with this risk rule. Paper trade only.

Exit Rules

When to get out

T

Target exit — take profit

When the premium has risen +40% to +45% from your entry, exit fully. The tool shows this in the Target Reference card. Theta erodes gains quickly if the move pauses.

S

Stop loss — cut immediately

When the premium falls 30% below your entry, exit without hesitation. No averaging. The signal did not follow through — the thesis is broken.

T

Time exit — hard close by 1 PM

Exit all positions by 1:00 PM, even if in profit or small loss. After 1 PM, theta decay accelerates and intraday moves become unpredictable.

Discipline

Rules to live by

ALWAYS DO THIS

Wait for 15% dominance spread before entering
Check VWAP before every entry
Calculate lot size before placing order
Wait until after 9:20 AM for any signal
Exit by 1 PM regardless of position
Skip the day if VIX is above 20

NEVER DO THIS

Enter when spread is under 15%
Trade against VWAP direction
Average down on a losing position
Move stop loss further to avoid a loss
Take more than 2 trades in one day
Trade on expiry day

Example Trade

What a good setup looks like

Sample CE trade

ATM strike: 23450 · Index: NIFTY · Expiry: 16JUN2026
9:15 CE premium: ₹98 | PE premium: ₹175

At 10:20 AM (auto-refresh running):
CE premium: ₹160 → CE% = +63.3%
PE premium: ₹109 → PE% = −37.7%
Dominance spread: 63.3 − (−37.7) = +101% ✓
Nifty vs VWAP: Above ✓

→ CE SETUP ACTIVE ▲ — observe bullish setup
Reference entry: ₹160 · Stop reference: ₹160 × 0.70 = ₹112
Target reference: ₹160 × 1.45 = ₹232

CE crosses dominance threshold cleanly — spread exceeds 15% with CE positive and PE clearly negative. VWAP above confirms. Enter with a limit order at the current CE premium shown in the Osprey tool.

Scenario 2 PE trade — bearish day, 15% dominance met

CE % change PE % change Signal zone

Mirror image of Scenario 1. PE dominates — buy PE, not CE. Nifty is below VWAP. Same 15% dominance rule, opposite direction. Same exit levels.

Scenario 3 Choppy day — spread never reaches 15%

CE % change PE % change False threshold

CE briefly touches +10% three times but spread never exceeds 15% — PE is not negative enough to give dominance. The tool shows "Spread X% — need ±15% dominance". The correct action: close the tool and do nothing. No trade is a valid outcome.
