Best Free TradingView Indicators for 0DTE SPY Options: A Trader's Guide

You’re staring at a 1-minute SPY chart. Your 0DTE option is bleeding theta by the second. You’ve got a dozen indicators on your screen — but they’re all saying different things, and you’ve got seconds to decide whether to pull the trigger or cut the loss.

If that sounds familiar, you’re not alone. The challenge with 0DTE (zero days to expiration) SPY options isn’t finding indicators — it’s finding the right ones, and knowing how to read them in the heat of the moment. Here’s a curated look at some of the best free TradingView indicators for 0DTE SPY trading, and why the tools you use after the trade matters just as much.

Why 0DTE SPY Demands a Different Toolkit

Trading 0DTE options is a different animal than swing trading or even trading longer-dated options. With time decay accelerating exponentially as expiration approaches, you can’t afford lagging signals or analysis paralysis. The best indicators for this game are built specifically for the unique dynamics of same-day expiry: institutional flow, volume deltas, volatility context, and pinpoint entry timing.

The Standout Free Indicators for 0DTE SPY

1. [Thies] 0DTE SPY+ES Volume, VIX1D, Volume Delta

Volume is the lifeblood of day trading, but raw SPY volume alone gives you an incomplete picture. Institutional flow is split across multiple instruments — ES futures lead price discovery and show institutional hedging, while SPY captures retail and ETF arbitrage .

This indicator solves that problem by combining SPY volume (blue columns), ES volume (orange columns), and a combined volume line (purple) into a single pane. The volume delta histogram (green/red) acts as a signed-volume proxy, showing net buying versus selling pressure. The VIX1D overlay is arguably its most valuable feature — it tells you the implied volatility regime for the current day, unlike the standard 30-day VIX, which is mostly irrelevant for 0DTE .

How to use it: Look for bullish alignment when the green delta histogram is rising, combined volume is above its moving average, and VIX1D is stable or falling. Conversely, a red delta histogram falling with combined volume above MA and VIX1D rising signals a bearish setup .

2. OptionSense Predict Map

For traders who want to see the broader picture without clutter, the OptionSense Predict Map visualizes key options-driven price zones directly on the chart . It highlights 0DTE resistance and support walls, weekly and monthly pressure zones, and high-probability scenario ranges. It even tags areas as "NO CALL" or "NO PUT" — zones where chasing is unfavorable — helping you avoid the chop that eats 0DTE accounts alive .

3. SPY / SPX Intraday Pro v31

This is not a generic indicator — it’s a complete intraday trading system built specifically for SPY and SPX 0DTE options on the 1-minute timeframe . The script reads market structure from the top down: the 15-minute chart establishes the primary bias, the 5-minute confirms structure, and the 1-minute acts as the execution layer. All three timeframes must agree before a high-quality signal fires .

4. Ripster + RVOL + Saty ATR – Options Dashboard

This all-in-one dashboard answers four questions every options trader should ask: Is there enough range left today? Is there real participation? What direction has the higher probability? And is now a good time to enter?

The DTR (Daily Trading Range) vs ATR percentage is especially useful — if the market has already used up most of its expected daily range, entering a new 0DTE trade exposes you to unnecessary theta risk without much potential reward .

5. 0DTE Breakout Framework – EMA Pullbacks + Bias Box

This indicator focuses on a single objective: catching clean trend continuation moves while avoiding chop and emotional trades . Its Dynamic Bias Box is a live decision panel that tells you exactly how to behave — "Calls Only above PMH," "Puts Only below PML," or "No trades – wait for EMA alignment." The Chop Zone Detection warns you when price is stuck inside the premarket range, which is where most 0DTE losses happen .

The Missing Piece: Managing Your Trades After Entry

Here’s where many traders get it right on the entry but fumble the execution. You’ve identified a high-probability setup using these indicators. You’re in a trade. Now what?

With 0DTE options, every second counts. Having to switch windows, pull up a bloated trading platform, or hunt for your position in a sea of open charts can cost you precious seconds — and profits. This is where a tool like Camovia Tray comes in.

Designed for traders who use MetaTrader 4 or 5, Camovia Tray turns your trading terminal into a system tray tool. Instead of keeping your MT5/MT4 window open and visible — taking up screen real estate and potentially exposing your positions to prying eyes — you can hide it completely from the taskbar and Alt+Tab view.

You can then check live quotes and manage your open positions directly from your system tray. Need to see the current P&L on that 0DTE SPY call you just entered? Hover over the tray icon. Need to close a position quickly as a key level breaks? Click the order card and confirm the close. The data is read directly from your local terminal and never leaves your machine [Product Knowledge].

For traders juggling multiple charts, indicators, and execution windows, keeping the terminal accessible but out of the way is a workflow efficiency that directly improves reaction time. It also helps maintain privacy in shared workspaces without relying on "stealth" narratives — it simply puts you in control of your setup.

Putting It All Together

The best approach to 0DTE SPY trading is to pick indicators that complement each other, not ones that overlap. A common setup might look like this:

• Use the SPY+ES Volume, VIX1D, Volume Delta for tape reading and volatility context .
• Use OptionSense Predict Map for key levels and scenario planning .
• Use the 0DTE Breakout Framework for bias and chop avoidance before entering .
• Once in the trade, use a tool like Camovia Tray to keep your terminal accessible but unobtrusive, allowing you to manage the position quickly and securely without disrupting your analysis flow.

A quick word on the "free" aspect: Most of these indicators are open-source or community scripts on TradingView, meaning you can add them to your chart and start using them today. However, free doesn't mean low-quality. Many of these community-built tools are more sophisticated and purpose-built than paid alternatives.

0DTE trading is one of the most demanding forms of active trading. The right indicators give you an edge in reading the market. The right workflow tools keep you in control when it matters most.
