Frequently Asked Questions
Why not just use a free stock screener?
Free screeners rank stocks by price, volume, or analyst ratings — none of which tell you whether a put is worth selling. SignalGreeks scores every S&P 500 stock specifically for options selling: IV quality, technical trend, liquidity, fundamentals, and premium yield are combined into one Put Opportunity Score, refreshed every 5 minutes during market hours.
What exactly is the Put Opportunity Score?
A 0–100 score weighing five pillars: IV Quality 30%, Technical 25%, Liquidity 20%, Fundamentals 15%, Premium Yield 10%. Stocks are auto-disqualified if earnings are within 7 days, market cap is under $5B, or bid-ask spreads are wide — so you only see candidates you can actually trade.
I'm new to selling puts. Is this for me?
Yes, if you want income-focused strategies. The score does the screening work; the Basic plan's Top-10 results are a manageable starting list. The score is also customizable — "wheel trader" and "income trader" presets let you match the ranking to your strategy as you learn.
Why should I trust this over the big platforms?
Transparency. The page shows the exact pillar weights above — most scanner sites hide their methodology. You see the inputs, the score history for every stock over 30 days, and the full options chain (bid, ask, IV, Greeks, open interest, volume) behind each recommendation.
Can I try it without committing?
The Basic plan is $15/month, and the 30-day trial starts immediately. You can finish signup without a card and add one later in Settings. Cancel any time before day 30 and you pay nothing.
How fresh is the data?
The scanner evaluates all S&P 500 stocks every 5 minutes during market hours. The daily Top-10 digest is emailed at market close, ready before the next session opens.
