Educational only, not financial advice. Broker features, options-approval requirements, 0DTE availability, and fees change and vary by account — verify current details on the broker’s own site. NoVo is independent and not affiliated with the brokers named.

Fidelity is the full-service giant of this list — retirement money, research, and a serious trading front end in Active Trader Pro. Scalping 0DTE SPY options here feels different from the app brokers: more machinery, more friction, more safety rails.

Approval is an application, not a toggle

Fidelity grants options by tier, and the entry tier covers buying calls and puts. It is a proper application — reviewed, not instant — so sort it well before the morning you want to trade, and confirm same-day expirations are available on your account type (does my broker offer 0DTE SPY).

Find the chain in ATP or on the web

Quote SPY, open the option chain, filter to today’s expiration (SPY lists a 0DTE every weekday). Active Trader Pro lets you strip the chain down to what a scalper needs — bid/ask, volume — so read the quote, then pick a strike: the responsive near-the-money strike, not the far-OTM lottery ticket.

Use the conditional-order machinery

Place the order at one contract. Fidelity’s ticket supports attaching contingent exits at entry — use it: set your stop as part of the order, because decay is fast on same-day contracts and a hard stop beats a mental one. Have the exit decided so you never drift into the close.

Fidelity gives you institutional-grade plumbing. Plumbing moves water; it doesn’t tell you where the river bends.

The part no broker gives you

Even the best order machinery executes a decision it cannot make for you. That’s where NoVo fits: it maps the dealer levels on SPY, QQQ and IWM and keeps a scored record of what that structure has tended to mean. It does not connect to Fidelity or any other broker — you place every trade yourself. Either way: start small, and remember levels are structure, not signals.
