What makes Gekko different

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.

GOOGL price chart with insider, options, hedge fund, politician and reversal markers plotted on the bars

Every marker is clickable. Hover one to see who bought, how much, and on what date.

●

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

What Buffett, Ackman, Coleman and ninety more did with the stock last quarter, from their 13F filings — one marker per quarter showing whether more of them were buying or selling, with the names on hover.

◆

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.

○

Buybacks

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

↑↓

Volume thrusts

A forceful one-day move on heavy volume, closing near its own extreme, arriving after the stock has been beaten down or run up.

★★

Candle patterns

Hammers, engulfing bars, kickers and morning and evening stars — the reversal candles worth knowing, filtered by where they printed and by the GekkoIndex so you only see the ones that matter.

▲▼

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 and 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 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, and check how a stock has historically behaved after entering each zone — 5, 10, 20, 30 and 50 trading days out.

Experience the power of TrendCandles™

Our new chart type colours every candle by the strength of the trend, so you can spot potential turning points and developing trends early.

Gekko.app TrendCandles chart type colouring each candle by trend strength, showing a downtrend fading through yellow into a developing green uptrend

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 you get positioning and trend in a single view.

Swing trading software built by a trader who uses it every day

Gekko was built by Jared Mann, a trader with more than 20 years of experience in stocks and ETFs and a financial industry background. It is the tool he uses every day, shared with more than a thousand active traders around the world.

Jared was tired of using dozens of different tools to find the data behind a good trade, and so Gekko was born: the all in one smart money research platform. Read Jared's story →

Questions, answered

Frequently asked questions

What exactly is Gekko?

Gekko is a research and analytics platform for US stocks and ETFs. It gathers the footprints that institutions, company insiders and politicians 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, a screener, 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 tools?

Two things. First, the chart: insider buys, options flow, politician disclosures, buybacks, 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 proprietary layers you cannot get elsewhere: the GekkoIndex™ score and Gekko Fair Value, both calculated in-house and shown on every ticker. It is built by a long-time active trader with a financial industry background, not a data vendor.
