How to Trade SPX Options | TTR 1DTE Strategy

A Smarter, Simpler Way to Trade SPX Credit Spreads

Looking for a data-driven way to trade SPX credit spreads without sitting at your screen all day, triggering pattern day trading (PDT) issues, or guessing which days are best?

Meet the TTR 1DTE Credit Spread System from Alpha Crunching—a strategy that returned a 37.6% compound annual growth rate over the past couple of years by risking just 2% per trade, with only one trade at a time.

‍

What Is the TTR System?

At the heart of this strategy is the TTR, or Tomorrow’s Triumph Rate. This exclusive Alpha Crunching metric tells you the percentage of times the SPX has closed higher the following day based on recent market behavior.

The data updates every weekend, so you’ll know in advance which days of the week are statistically favorable for placing trades.

‍

How the Strategy Works

Check the TTR each weekend — look for days with a TTR of 60% or higher that is flat or increasing week-over-week.
Only trade on valid days identified by Alpha Crunching’s Trade Ideas tab, updated every Sunday.
1DTE trades only — simple, short-duration trades with a defined edge.

‍

TTR Weekly Trade Setup

The system follows a structured schedule:

Put Credit Spreads on Monday, Wednesday, and Friday
Call Credit Spreads on Tuesday and Thursday

‍

Each trade idea comes with:

Time of day to place the trade
Strike selection
Management rules
Historical performance data
A link to a deep-dive article for added context

‍

For the Tuesday/Thursday CCS example shown in the video:

75% win rate
$204 average win
$284 average loss
Smooth, consistent P&L curve
