Key Points

✓ Get Paid to Wait: Collect premium instantly for promising to buy a stock you already want.
✓ Lower Cost Basis: If assigned, your entry price is significantly lower than the current market price.
✓ High Probability: Statistical edge is in your favor; you win if the stock goes up, flat, or drops slightly.

Why Buy at Market Price?

When you place a Limit Order to buy shares of Apple at $190 (when it's trading at $200), you are providing a service to the market. You are providing liquidity. But usually, you do this for free. You sit and wait.

The Cash-Secured Put allows you to get paid for that service. By selling a put option, you obligate yourself to buy the shares at your target price, but you collect a cash premium upfront. If the stock never drops, you keep the cash. If it does, you get your stock at a discount.

How It Works

The Mechanics

1.
Select Stock & Strike:
Stock: XYZ at $100. Strike: $90.
2.
Secure Cash:
You must have $9,000 cash in your account (100 shares * $90) to cover the potential purchase.
3.
Sell Put & Collect Premium:
You sell the Put and instantly receive $200. This cash is yours to keep forever.

The Discount Math

Selling puts effectively lowers your purchase price below the strike price. Use the calculator to see your "True Cost Basis."

Win-Win Scenarios

Unlike buying stock, where you only win if it goes up, selling puts gives you three ways to win.

Market Move	Stock Buyer	Put Seller
Rallies 🚀	Profits	Keeps Premium (Max Profit)
Flat ➖	Nothing	Keeps Premium (Income)
Drops Slightly 📉	Loss	Keeps Premium (Buffer)
Crashes 💥	Big Loss	Owns Stock (But at discount)

Picking the Right Strike (Delta)

How aggressive should you be? It depends on whether you actually want the stock or just want the income.

The "Income Hunter" (30 Delta)

Sell a strike that is further OTM. ~70% chance of expiring worthless. Lower premium, but higher safety margin. Use this if you prefer cash over stock.

The "Stock Acquirer" (50 Delta)

Sell a strike right at the current price (ATM). Highest premium. ~50% chance of assignment. Use this if you really want to own the shares now.

The Catch (Risk Management)

The risk is not losing money; the risk is **buying a bad stock**. If you sell a put on a company that goes bankrupt, you are still obligated to buy shares at the strike price, even if they are worthless.

The Golden Rule:

"Never sell a put on a stock you wouldn't be happy to own for the next 5 years."

The AI Edge: Finding Put Walls

The best place to sell a put is at a major support level. But charts can be deceiving. TradeAlgo tracks "Put Walls"—levels where institutions have sold massive amounts of puts. These levels act as a magnetic floor for the price.

Why Follow the Walls?

When price drops to a Put Wall, Market Makers often have to buy stock to hedge, creating a natural bounce. Selling your put at this level dramatically increases your win rate.

Don't Buy. Get Paid to Buy.

Change your mindset from "chasing" price to "setting traps" for price. Use our institutional data to find the strongest support levels.
