Live NIFTY · SENSEX · BTC · ETH
CoTrader is the live terminal for options sellers. Option chain with Greeks, rolling straddle, implied vs realised volatility, open-interest walls and a payoff-based strategy builder, with every number showing its evidence.
Brokers are built to take orders. Sellers need to see risk, context and volatility before they sell.
Implied volatility next to what the market is actually realising, converted to the same time basis so the comparison is fair.
The straddle-implied range drawn on the chart, with breakevens shown in standard deviations.
Call and put walls by strike, PCR and change in OI, so you see where positions are stacked.

Every panel is yours to move, resize, minimize or maximize.

Straddles, strangles, iron flies and condors, credit spreads. Payoff, breakevens, probability of profit, net Greeks.

We tested the usual claims on years of minute-level data. Most indicators did not hold up. So CoTrader does not sell you signals.
"The market prices options fairly most of the time. A good terminal does not pretend otherwise. It shows you the risk, the context and the numbers, and gets out of your way."

No. CoTrader shows market data and planning tools. It does not recommend trades, give tips or issue signals, and it is not a registered investment adviser or research analyst. Read the risk disclosure.
Never. You place and manage every order with your own broker. CoTrader is where you read the market and plan the trade.
Yes. The terminal refreshes every second from a live market feed, and the header shows when the feed is live, delayed or offline.
NIFTY 50 and SENSEX options today, with BTC and ETH prices in the header. BTC and ETH option chains are planned.
No, and we say so. They describe conditions, and each one shows how it has behaved historically. In our own testing most indicators gave no durable edge, which is why we show evidence rather than promises.
Not to explore the terminal. You will need one to place trades, with the broker of your choice.
The layout adapts to smaller screens by stacking the panels. A dedicated mobile view is on the roadmap.
