ORTEX Options PlatformNew

The only options chain with short interest on it.

Options flow and unusual options activity, gamma exposure (GEX), IV rank, max pain and expected move, next to the ORTEX short interest data that explains them. A full chain with live Greeks across every expiry from 0DTE to LEAPS, plus earnings implied-move and IV-crush history.

And analyze the trade before you place it: build any multi-leg strategy and see the full P&L curve, at expiry or any date in between, with probability of profit computed for you. The return potential of a complex spread becomes a picture, not guesswork.

01
Short interest on the chain
SI % of free float, days to cover and the borrow fee, next to every strike. Context that changes the trade on any crowded name.
02
The ORTEX Short Score
One balanced 0–100 number that weighs everything affecting a stock's short interest. A high score means the setup for a potential squeeze is in place; from there it just needs a catalyst, usually a rising price.
03
SI + open interest overlay
Thirty days of short-interest change and options OI build-up on one axis, to spot positioning before it becomes a headline.

A $9.90/mo add-on to any ORTEX plan (shown in your local currency). Launch offer: half price for your first 6 months.

The strategy analyzer turns any position into a picture. Below: a call butterfly on TSLA, anchored to the live price. The white line is your profit and loss at expiry, the curves show today and any date you pick, green is where the trade wins and red is what it risks. Breakevens, max profit, max loss, Greeks and probability of profit are computed for you and update as the price moves. And when you need candidates, the IV screener and the Short Score surface the setups worth analyzing in the first place.

ORTEX forecasts · Index Rebalance

See the forced trades before they’re announced.

Passive funds overtook active in early 2026, and around $13 trillion now tracks the S&P 500 alone. When a stock joins or leaves an index, those funds have to trade it at any price. ORTEX forecasts which stocks move in and out before the official announcement for 47 indices across 13 markets, MSCI included, every trading day before the open, with a conviction score from 0 to 0.99 and an estimate of the passive flow each change will trigger.

ORTEX BacktesterNew

Would your idea have made money? Now you can find out.

The ORTEX Backtester turns the whole data platform into a laboratory. Describe a trading idea in plain rules, then replay it across years of real market history. No code, no spreadsheets: you see every trade the idea would have taken, and whether it actually worked.

The power is in the inputs. Your rules can draw on the same data professional desks pay for, short interest and cost to borrow, technicals, fundamentals, options activity and corporate events, hundreds of data points and millions of ways to combine them, so you can finally answer questions like: what would buying oversold stocks with rising short interest, and closing them when the pressure eased, have returned?

And when a backtest earns your confidence, switch it on: ORTEX runs the same rules against live data and alerts you when a stock meets them, with the position the strategy would take, ready for you to review and action right away.

01
Pick your universe
A region or one of your portfolios, narrowed by market cap and industry. Up to 2,500 stocks in a single run.
02
Describe the setup you'd buy
In plain rules, no code: price moves, short interest, RSI and MACD, fundamentals, options activity and corporate events, combined with AND / OR.
03
Decide how you exit
Stop loss, profit target, a time-based exit, or a condition that closes the trade when the signal reverses. Set once, or per setup.
04
Run it and read the verdict
ORTEX replays history rule by rule and returns the return, CAGR, Sharpe, drawdown, win rate and a ledger of every trade.

Backtests are hypothetical simulations run on historical data. They do not account for trading or borrowing costs, slippage, taxes or available liquidity, and real results would differ. Any strategy shown is an illustration of how the tool works, not a recommendation to buy or sell any security, and nothing here is investment advice or a personal recommendation. Past performance is not a reliable indicator of future results; the value of investments can go down as well as up, and short selling carries additional, potentially unlimited risk. Data may contain errors, so validate independently before acting. See our Terms & Conditions and the full disclaimer at the foot of this page.

ORTEX Charts · For your productNew

The chart engine behind ORTEX, for your own data.

We built our own charting engine for the ORTEX platform because nothing on the market handled deep histories, order flow and hundreds of series without slowing down. Now it is a commercial JavaScript library for brokers, trading platforms and research sites. It ships without data: you plug in yours, and it draws it fast and beautifully.

Your data, drawn beautifully. Feed it prices, fundamentals or any time series of your own. Plot as many lines as you need, each on its own axis or pane.

A data menu built in. Users add and remove series from a menu you define. Your own feeds go in it, and ORTEX data can too, through the API, if you want it.

Styled as your product. Colors, fonts, toolbar and layout are yours to set, with no mark on paid plans. White-label and OEM by agreement.
