I completely switched over to Gekko from TradingView for all my charting and stock research needs because it has everything TradingView has plus some very useful smart money data and trading signals with GEX levels on the charts too, which I use to find entry points on swing trades.

You've developed a truly awesome platform. The depth of data and features along with all the custom indicators makes Gekko feel different from anything else out there — a whole new level of stock trading tools indeed.
This has become part of my daily routine. Options flow right on the charts is something I actually look forward to checking. Hard to go back to piecing it together from three different sites.
I searched for something that shows insider and institutional activity without a Bloomberg terminal. This gets closer than most. See smart money signals on the charts is what got me with Gekko. Highly recommended!!
I moved over from a couple of other platforms and haven't looked back. Having insider buys, options flow, and the index score visible on one chart cuts the noise way down. This one actually stuck.
Gekko is awesome for finding solid trade setups other tools don't do. Instead of checking multiple sites for filings and flow, most of it is already plotted. See the smart money buys and sells on charts is very handy to have thanks a lot for developing this.
I can tell gekko.app was developed by trading professionals with plenty of experience, I love how simple it is to use, better than expected for spotting institutional footprints. Mostly use the insider trades and options flow to spot opportunities.
Gekko tracks smart money data in one place better than anything else I've tried at this price. Options flow ranked by premium and direction is the first thing I open. Charts are fast and the whole thing just feels well thought out.
I open gekko every morning before the bell and honestly feel off if I skip it. Options flow feed plus the fair value number next to the index score gives me a quick filter that just works. One of the better tools I've added in a while.
Mainly here for the insider buy markers and volume thrust signals. Having them right on the price chart is more practical than reading separate tables. No real complaints after three weeks of daily use.
Like how the signals sit directly on the bars. No constant date cross-checking. Used the rotation and breadth tools a few times when the market got choppy. Straightforward product overall.
Does a clean job of putting smart money footprints on the chart where they belong. Buyback and politician trade markers are bonuses I didn't expect to use as often as I do. Genuinely useful.
This is a great app for swing trading which I'm into. The screener sorted by GekkoIndex has surfaced a few names I would have missed. Chart signals are clear. Being able to use the trade optimizer to set stops and profit targets is very useful.
I check the options flow and GekkoIndex first thing every session. Having both the score and the fair value estimate in the same place speeds everything up. This one earned a permanent spot in the morning lineup.
I replaced a couple of paid data services with this and haven't missed them. The combination of index score, flow, and insider markers covers most of what I was piecing together before. Reliable and actually enjoyable to use.
The historical view of what tends to happen after a stock enters the buying zone is one of the more interesting parts. Not a crystal ball, but useful context. Feels built by someone who actually trades and understands the workflow.
I've been using stock trading software for years and Gekko is different from anything else out there. Politician trade markers and buyback data turned out to be features I didn't know I needed. Occasional lag on the heatmaps during high-volume periods, otherwise solid.
Killer tool you guys developed!! Options flow and insider signals are the strongest parts. The rest of the tools are nice to have but seeing signals on charts does it for me.
Solid tool for tracking insider activity without constantly jumping between SEC filings and price charts. Signals are dated to the public disclosure, which is how it should be. Interface is clean once you settle on the layers you actually want visible every day.
The trade planner and backtester surprised me in a good way. Not trying to predict anything, just checking historical context around similar signals. Gekko.app has quietly become one of those tools I don't want to trade without.
What you guys developed is pretty unique. Fair value estimate next to the GekkoIndex is a nice touch. Caught a couple of accumulation setups earlier because of it. Only feedback I would say is the mobile version works okay but feels less smooth than desktop.
Daily dashboard summary is handy. Top GekkoIndex names and the live options flow give a quick read before I open individual charts. Haven't run into any major issues after six weeks.
Gekko does a good job organizing public data that used to be scattered everywhere. Mostly watch the accumulation and buying zones. Fair value estimate works as a secondary check.
Run the screener most mornings sorted by GekkoIndex and sector. A few names have shown up early enough to be useful. Chart overlays are clear and the hover details save time.
I enjoy using gekko regularly and use it to confirm whether there's any institutional footprint before sizing a position. Volume thrust and reversal markers have been more relevant than expected.
Good overall experience. Index score and fair value side by side make a quick filter. Options flow feed is well ranked. Would like a couple more dashboard customization options. I sent customer support and they responded it would be done soon.
Been using gekko for the chart signals and the daily brief. Nothing flashy, just well-organized data that used to take longer to put together. Fits my trading style cleanly.
This is my new go to trading tool. Insider and options data on the charts are the main draw. Screener works well. A few of the secondary tools feel less polished than the core features.
I log into Gekko everyday, new features seem to get added without extra cost, which is appreciated. Mostly live in the charts and the screener. Interface is straightforward once the layers are set the way I want them.
Good platform for the price! Chart signals are clear and the GekkoIndex zones give a quick read. Heatmaps and rotation tools are secondary for me but still helpful on quiet days.
I use gekko to stay aware of institutional activity without spending half the morning on filings. Options flow and the index are the two features I rely on most. Does the job without drama.
Gekko is practical and focused. Signals on the chart, a usable screener, and the fair value number are enough for my process. Gekko.app feels like it was put together for people who already do their own research rather than beginners looking for tips.
Useful for what it is. GekkoIndex is a decent starting point and the options data beats free alternatives. Layout gets crowded if you turn every signal layer on at the same time.
Does some things well, especially the chart markers for options and insiders. GekkoIndex still feels a bit like a black box and the screener could use more filter options. Still better than assembling the data myself from multiple sources every day.

Every smart money signal on one stock chart
Everywhere else you hunt through separate tables for insider filings, options activity and congressional disclosures, then try to remember where the price was at the time. Gekko draws them straight onto your chart, on the day each one became public.
●
Insider buys
A CEO, CFO or 10% owner buying their own company's stock with their own money — the one trade nobody makes by accident.
●●
Options flow
Unusually large call and put positions, measured against the size of the company rather than a flat dollar figure — so mid-caps show up, not just the mega-caps.

Hedge funds

Politician trades
Congressional and Senate disclosures, plotted on the day they became public — not the trade date, which can be up to 45 days earlier.
Analyst calls
Upgrades, downgrades and new coverage — but only from analysts ranked in the top thousand by their career track record, so a marker means a call worth noticing.

Buybacks
The company itself announcing it is buying back its own shares, pulled straight from the SEC filing.

Reversals
Price exhaustion after a run of consecutive new highs or new lows — a marker for where a move ran out of road.
Built to be read at a glance
Position tells you direction before colour does. Bullish markers sit below the bar, bearish above it — you can read the chart before you have processed a single colour.
Hover any marker for the detail behind it: the contract, the size, the date. Toggle each layer on or off, draw your own trendlines, zones and Fibonacci levels, switch between daily and weekly bars, and move between one month and five years of history.
Every marker family owns its own shape and its own place in the stack, so the chart stays readable even when several land on the same day.

Our flagship indicator
One score for the whole smart money picture
The GekkoIndex™ is a 0–100 score on every stock and ETF, updated every fifteen minutes through the trading day. It takes the institutional footprints scattered across filings, flow and price behaviour and turns them into one number you can read at a glance — the anchor the rest of Gekko is built around.
Sort the market by it, filter by it, plot it over price, set an alert on it, and check how a stock has historically behaved after entering each zone, over five horizons — from the next fifty trading days out to the next five hundred.

See where the options market pins the price
GEX Levels draws the Call Wall, the Put Wall and the Gamma Flip on the chart from the full options chain, recalculated nightly for around 2,000 stocks and ETFs. The Dark Pool Index adds what off-exchange volume is doing underneath. Two things traders used to pay separate subscriptions for, now on the same chart as the insider buys.
MRNA in positive gamma: price ran from the Gamma Flip to the Call Wall, with the Dark Pool Index above its normal range the whole way.
Call Wall $227.50
Where rallies stall
The strike above price carrying the heaviest call positioning. Dealers hedging it tend to sell into strength as price approaches, so it often acts as a lid — and as a target for a swing already underway.
Put Wall $200.00
Where sell-offs find a floor
The mirror below price: the strike with the heaviest put positioning. Hedging flows tend to buy into weakness here, which is why it so often marks support — and a place to look for a swing entry.
Gamma Flip $181.83
Where the regime changes
Above the flip, dealer hedging dampens moves and dips get bought. Below it, hedging amplifies them and moves run further than they should. The readout tells you which side of it a stock is trading on today.

Experience the power of TrendCandles™
Our chart type colours every candle by the strength of the trend, so you can spot potential turning points and developing trends early.
Deep green to deep red, with every shade between. The colour is the trend — read the whole chart in one pass.
The turn shows up before the breakout
Candles pale as a trend loses its grip and deepen as it takes hold, so a move that is quietly changing character looks different long before it clears an obvious level.
Works on every ticker, day one
No warm-up period, no minimum history and no dependency on any other signal. Every US stock and ETF we cover, on daily or weekly bars.
Proprietary to Gekko
Built in-house and available nowhere else. Sit it alongside the smart money markers and GEX levels and you get positioning, trend and the options pressure points in a single view.

Questions, answered
Frequently asked questions
What exactly is Gekko?
Gekko is a stock charting and research platform for US stocks and ETFs. It gathers the footprints that institutions, company insiders, politicians and the options market leave behind in public filings and market data, then plots them on charts and organises them into feeds, screens and scores. You get the proprietary GekkoIndex™, Gekko Fair Value, GEX Levels and the Dark Pool Index, 24 chart indicators, a screener, AI-generated trade ideas, alerts, a backtester and a full market analysis toolkit across 5,800+ tickers, all in one dashboard.
Do I need a credit card for the trial?
No. Sign up with an email address and you have full access to every feature for 7 days. Nothing is charged, and there is nothing to cancel if you decide not to continue.
What makes it different from other charting tools?
Three things. First, the chart: insider buys, options flow, politician disclosures, buybacks, analyst calls, volume thrusts and reversals are all drawn on the price itself, dated to when each became public — most platforms leave that data sitting in separate tables. Second, the indicator library: GEX Levels and the Dark Pool Index from the options chain and off-exchange data, plus Gekko's own TrendCandles™, Gekko Bands, S&R Clouds, Smart Money Score and Dynamic Swing Index. Third, the proprietary scores you cannot get elsewhere: the GekkoIndex™ and Gekko Fair Value, calculated in-house and shown on every ticker. It is built by a long-time active trader, not a data vendor.
Does Gekko show GEX levels, gamma exposure and dark pool data?
Yes. GEX Levels draws the Call Wall, Put Wall and Gamma Flip on the chart for around 2,000 optionable US stocks and ETFs, recalculated from the full options chain every night, with the net gamma regime, max pain and an optional strike profile. The Dark Pool Index shows a stock's daily off-exchange short-volume ratio from FINRA data against its own normal range. Both are included in every plan and the trial — no add-on. More about GEX Levels & Dark Pool →
Is this real-time, and do I need TradingView as well?
Prices and the GekkoIndex refresh every fifteen minutes during the US session, and every filing lands on the chart the day it becomes public. Gekko is a research and charting platform rather than an execution terminal, so there is no tick-by-tick tape — but it is a complete charting tool in its own right: chart tabs and saved layouts, seven chart types, drawing tools, moving averages, alerts and the full indicator library. Many subscribers use it as their only charting platform.
Start seeing the footprints
The largest investors in the market leave a trail in public filings, options positioning and off-exchange flow. Gekko collects that trail, dates it, and puts it on the chart in front of you. Take a week and see what your own watchlist looks like with it turned on.
