Independent comparison for prospective users. NoVo is not affiliated with the tools named. Features and pricing change often — this page deliberately avoids quoting specific prices, because they go stale. Check each provider’s own site for current numbers.
Both categories are legitimate. They answer different questions, and buying the wrong one first is the most common expensive mistake in this space.
Options flow: what was traded
A live record of transactions — sweeps, blocks, unusual size. Useful if you believe large participants carry information and you want to follow them, typically across many names. NoVo reads its own version of this in-house off the live tape — sweeps & blocks for SPY, QQQ and IWM — on the Analyst dealer map.
Gamma levels: what dealers must do
A map of dealer exposure and the hedging it forces as price moves. Useful if you trade an index intraday and want to know which prices are likely to pin, repel, or accelerate. It is structural rather than anecdotal — the same levels matter until positioning changes.
Which to buy first
Buy flow first if you trade single names on catalysts and your process is following size. Buy levels first if you trade SPY, QQQ or SPX intraday and your process is levels-and-reaction. Most 0DTE index scalpers get more from levels, because the intraday tape is dominated by hedging flows.
Flow tells you what someone else did. Levels tell you where the market is likely to be forced next. On an index, the second is usually the better first purchase.
The part neither solves
Data is not a trade. Whichever you buy, the strike, the size, the stop and the exit are still on you — unless you buy a tool where the read and the execution are the same product.
Where NoVo is the wrong answer
NoVo covers 0DTE/1DTE on SPY, QQQ and IWM and nothing else. If you need multi-ticker research, equities screening, futures gamma or macro commentary, a dedicated analytics platform is simply the better purchase. NoVo also never enters a trade on its own — you click every entry. And it does not reduce market risk: options carry substantial risk of loss, which is why paper mode exists.
