Sell Premium.
Let Theta Work.
OptionsDecay.com is built for systematic options sellers. Learn how professional traders use theta decay, iron condors, and rule-based automation to collect consistent premium income from the SPX — every trading day.
Option Selling
Theta decay erodes option value every hour. As a seller you collect premium upfront and profit from time — in flat, mildly bullish, and mildly bearish markets alike. The statistical edge is on your side.
Why sell options →0DTE SPX Trading
Zero days to expiration options on the S&P 500 Index offer the fastest theta decay available. Cash-settled, no assignment risk, and a fresh cycle every market day. Iron condors on SPX are the professional's instrument of choice.
Learn 0DTE trading →Bot Automation
Emotion and inconsistency are the silent killers of options strategies. Rule-based bots enter at the right time, exit at defined targets, roll adjustments automatically, and never second-guess after a losing day.
Automation deep-dive →Defined Risk
Every position has a known maximum loss before entry. Iron condor spreads cap your downside at the wing width minus credit collected. Position sizing, stop-loss rules, and adjustment logic keep a single bad day from erasing weeks of gains.
