Nightglass Reviews 

This is a tool built from the ground up, with a ton of feedback from the community. In essence this all the features/tools someone wants, which is then amplified with Kasm's (the creator) unique experiences.
Tools throwing out live option flows are aplenty. The concept of why an option flow matters and how actionable it is; how to apply it, usually takes some time to understand.
Live filtering through as many orders hit the tape, requires a seasoned eye, which takes years of active trading.
Option trading largely involves finding setups and then the right instrument(i.e. which strike/expiry) with which one can try to make money.
Nightglass combines a ton of the above and handles the tedious part for you, by highlighting those setups that are actionable, and therefore likely valuable.

I've tried to use many different tools in my trading journey, this is the only one that's stuck so far. One thing I love is the dev team is in constant search for feedback from the community or improvements to make to the tool. From my time with it, it's evolved immensely, and am very excited for the future.

Nightglass has become a part of my daily routine as a trader and extremely valuable to my workflow.

Honestly, I thought Nightglass would just be another mediocre flow service with a bunch of big options prints and not much else. I’ve tried other services before, and a lot of them feel like they’re just throwing data at you and leaving you to figure everything out yourself. Nightglass is much more than that.

What really stands out is how everything comes together. The flow is filtered, the alerts actually have context behind them, and having the chart levels and broader market information all in one place makes a huge difference. It feels like an actual trading tool rather than just another feed to stare at all day.

I also really like that it helps narrow down what’s worth paying attention to instead of overwhelming you with endless alerts. It saves time and makes the research process a lot more organized.

Overall, Nightglass has been a pleasant surprise. If you're serious about trading and want more than just raw options flow, it's definitely worth checking out. Easy 5 stars.

Nightglass has become my favorite resource. My routine starts with Nightglass now. I get my updates on the market and overnight events from the morning note in Nightglass. Then I it use it for its superior flow analysis and key levels for my favorite stocks. I keep finding better ways to use it and am continually impressed by it.

I use Nightglass flow everyday to scan the market for new trends and leaders. It is very useful for 0dte spx due to the GEX it provides. KASM is a brilliant mind who actively beats the market and very large hedge funds.

The options flow charts are in an easy to read format, unique and innovative. And the alerts are quite accurate. I observed them for a few weeks and I'm a believer now.

Nightglass is much more than an options flow platform. What I like most is that it brings a lot of the information I normally have to piece together from different tools into one place.

The flow alerts are great because they filter out a lot of the noise and give you direction, conviction, structure, and context instead of just throwing raw prints at you. But the real value for me is everything around the flow.
You can pull up a ticker and see key support and resistance, supply and demand zones, open-interest walls, positioning, and invalidation levels. You also have SPX dealer gamma and important index levels, market and sector context, earnings and catalysts, pre-market research, daily reports, momentum tracking, and historical flow data.
I especially like that Nightglass connects everything into an actual research process: find where unusual activity is happening, analyze the ticker and key levels, understand the broader market and gamma environment, and then review what happened afterward.
Another big positive is the transparency. They maintain a public scoring methodology and keep losing signals visible instead of only advertising the winners.
For an active trader, it feels less like another options scanner and more like a complete market research terminal. There is a lot of information available, but it is organized around actually helping you build and validate a trade thesis.

Nightglass is actually good.
Most flow tools just dump every big print on you and let you figure it out. This one filters first. You get like 75 alerts a day instead of staring at noise all session. It reads the structure so a spread doesn’t show up as two random legs fighting each other, and it tells you bullish / bearish / unresolved plus conviction.
The levels are the part I actually use. Flow tells you the name. The chart tells you where to do something with it. Premarket report is solid too if you don’t want to rebuild the overnight tape yourself.

If you already live in Unusual Whales / BlackBox / GEX, this is just a cleaner version of that workflow. It’s not going to trade for you. It just cuts the garbage so you can work faster.

Nightglass has essentially replaced my previous workflow for trading. While it started as an options flow platform that filtered out 'noisy' flow, it has matured into something approaching an all-in-one trade research workhorse. I get to read a best-in-class market summary before the trading day (Alpha Flow), see sector rotation and breadth in real time, plus all the preexisting options flow stuff that made NightGlass special in the first place. The ticker analysis with open interest 'walls' and built-in technical analysis is world-class and even overlays notable flow right on the chart.

The dev ships updates almost daily and has given us some previews of even more super cool features to come. I can't imagine trading without NightGlass anymore.

Created by a true professional that understands how options flow really works. canceled all other subscriptions cause this has it all.

Nightglass has it all ,from carefully filtered flow alerts that filters out the fluff and displays the alerts that matter to the trader, Alpha flow is the best way to get your day started ,it is a comprehensive report to digest the market moves from the prior day ,there are also other tools to check market breadth and momentum, if you are serious trader ,Nightglass should be your main arrow in your quiver

The nightglass app is really great at finding significant flow that predicts large moves, or helps you to exit positions when conditions are no longer favorable. Furthermore, the support/resistance levels seems to be very good at predicting changes of structure.

Nothing is clear
