## The 6-Step Checklist

### Step 1: Identify Large Trades

Look for SPX 0DTE alerts with:

- **Size:** >1,000 contracts
- **Value:** >$250K
- **Single-sided:** Calls OR puts only (not both - paired = hedge)

### Step 2: Check Market Context

Verify with price action:

- SPX has moved 1%+ today
- Trend is clear (not choppy)
- Volume is above average

### Step 3: Look for Far OTM Strikes

Best strikes are:

- 5-10% from current price
- Low premium ($0.50-$3.00)
- High potential leverage

### Step 4: Wait for Repeat Signals

Higher confidence with:

- Multiple same-direction alerts
- 5+ minutes of continuous flow
- Increasing size on each alert

### Step 5: Execute Quickly

Act within 5-10 minutes:

- Enter via your broker
- Set 20% stop-loss
- Target 50-100% gains

### Step 6: Manage the Trade

As it moves:

- Take 50% profit quickly
- Let runner ride to target
- Exit 1-2 hours before close

## NDX Morning Sniper Strategy

Capture quick gains at market open using Directional Trades or High Value 0DTE channels.

2. **Find OTM NDX Calls** - Look for calls above NDX price with >$250K value
3. **Trade with trend** - Only trade in the market's direction
4. **Act fast** - Enter within 5-10 minutes as prices spike
5. **Lock profits** - Exit at 50-100% gains quickly

### Important

NDX is extremely volatile - use smaller position sizes than SPX.

## When NOT to Trade

- Choppy, range-bound SPX (no clear trend)

- After 2 PM (time decay accelerates)
