A trader buys ten SPY 513 calls at $1.20 — $1,200 total. SPY sits at 511. His thesis: it grinds higher into the close.

He's right. SPY rallies nearly two points. And by 4pm the calls are worthless.

Here's the part worth remembering: his problem was never direction. With SPY at 511 and a 513 strike, every cent of that $1.20 was time value — zero intrinsic. He wasn't buying value. He was renting hope by the minute.

And time value doesn't decay in a straight line. It falls off a cliff in the last two hours. He bought at 1:30, right at the top of that cliff.

Watch the split:

• 3:00 — SPY up a full point from entry. Calls down to $1.10. Delta gave him thirty cents, theta took forty.
• 3:30 — SPY half a point from his strike. Calls at 80 cents. Down a third while being more right than ever.
• 3:58 — SPY closes 512.90. Ten cents short of 513. Settles worthless.

He nailed the direction and the scoreboard read zero. Because at expiration you aren't paid for being right. You're paid for being in the money before the clock runs out.

What a disciplined trader does: if you're buying 0DTE, buy closer to the money so delta does the work instead of hope. Exit by a clock, not just a price — if the thesis hasn't paid by a set time, the decay curve says leave. And size it like a lottery ticket, never like rent you can't lose.
