Your first 0DTE trade should be a single contract — small enough that the fast decay and volatility teach you without hurting you. 0DTE is the deep end, so you meet it small. Here's why one contract is the right call.

Why 0DTE demands respect on the first try

0DTE is leveraged and fast: premiums swing hard in dollar terms, theta bleeds relentlessly, and the tape can move violently. For a first-timer, that's a lot to absorb — and doing it with size would turn a learning experience into a potentially painful one. The behavior of a 0DTE option (how fast it moves, how it decays, how the close feels) is something you need to experience to understand, and you want to experience it cheaply.

What one contract buys you

A single contract lets you feel how 0DTE behaves — the speed, the decay, the swings — with a tiny, defined risk (one premium). You learn the real dynamics without fear clouding your judgment or a loss denting your account. It's the same logic as sizing any first trade small, but 0DTE's intensity makes it even more important. You're buying an education in how the instrument works — keep the price of that education low.

Meet 0DTE with one contract. Learn how the fast, leveraged, decaying thing actually behaves — cheaply, before you ever put real size behind it.

The quick takeaway

Your first 0DTE trade should be one contract — enough to learn how the instrument really behaves, small enough that its intensity can't hurt you. Scale up only after proven consistency. This is the disciplined way into the deep end, and it's exactly the small-first approach NoVo's risk-based sizing supports.
