Prices do not update

Live prices in QuantPower come from your connected broker account, so check the broker connection first.

CheckWhat to do
Broker sessionSessions end before each trading day. Log in to your broker again from QuantPower
Zerodha data subscriptionZerodha needs an active Kite Connect subscription (₹500 a month) for live prices
Market hoursEquity trades from 9:15 to 15:30 and F&O until 15:40. Outside these hours, prices do not change
HolidayCheck the exchange holiday list and the F&O expiry calendar
Broker outageCheck your broker's app or status page. The QuantPower status page lists known problems

Charts are blank or slow

  1. Reload the page.
  2. Use a current version of Chrome, Edge, Firefox or Safari.
  3. Turn off extensions that block scripts, then try again.
  4. Reduce the number of charts or indicators on screen.
  5. Check that the instrument has not expired. An expired contract shows no new candles.

Candles differ from another platform

Small differences are normal. The usual causes are:

  • Data source: prices come from your broker's feed, which can differ slightly from another vendor's.
  • Candle times: Indian intraday candles start at 9:15. A platform that starts at 9:00 or uses another time zone groups prices differently.
  • Adjustments: daily charts of stocks may or may not be adjusted for splits and bonuses.
  • Futures charts: a continuous futures chart joins contracts at rollover; a single contract's chart does not.

Indicators look different

Check the indicator's settings on both platforms: the period, the source (close, or high-low average), and for VWAP, when it resets. A 14-period RSI on 15-minute candles will not match a 14-period RSI on 5-minute candles.

Option chain numbers look wrong

What you seeLikely reason
A strike shows no priceIt has not traded today; look at the bid and ask
Open interest does not changeExchanges update open interest at intervals during the day
IV is very high on far strikesThin trading and wide spreads distort IV on far out-of-the-money options
Greeks are missingThey need a valid price; illiquid strikes may not have one
Prices frozen near or after the closeStocks with F&O contracts stop continuous trading at 15:15 for the closing auction, so index values pause until the auction result at about 15:35. After the close, values show the last trade

Data differs between the app and the web

Both use the same account and broker connection. Refresh both, check you are looking at the same contract and expiry, and check that the phone is connected to the internet.
