Hide CAS candles post 3.15 PM
Hide CAS ticks/ candles post 3.15 pm for NSE and BSE F&O equivalent cash stocks & Indices.
- Since 3 August 2026, F&O stocks on NSE no longer trade continuously till the close. Continuous trading stops at 15:15, and the last 20 minutes run as a Closing Auction Session (CAS) — a single-price auction that only prints at the end.
- The candles between 15:15 and the auction print stop reflecting normal supply and demand. You see wicks, gaps, and sudden spikes that have nothing to do with what buyers and sellers were actually doing.
- On higher timeframes (hourly, daily, weekly), that distorted tail gets baked into the bar's close, high, or low — quietly poisoning every study, moving average, and pattern you're looking at.
- Even the official Nifty closing level has jumped ~200 points at the fag end on some days purely because of CAS mechanics, catching seasoned participants off guard.
What this indicator does
- For NSE and BSE F&O equivalent cash stocks & Indices, ends every trading day at 15:15 on your chart, the moment continuous trading actually stops.
- Bars starting after 15:15 vanish. The 15:15 print shows as a small tick so you can see where the day closed.
- On hourly/daily/weekly bars, the close, high, and low are recomputed as if the market ended at 15:15 — no CAS contamination.
- Bars before the cutoff are left completely untouched. You see the real market, minus the auction noise.
Practical notes
- Only runs on NSE/BSE symbols that have an F&O contract (those are the ones CAS affects).
- Only works on candles starting 3 Aug 2026
- Cutoff time and start date are configurable — leave defaults for CAS, or shift them if a future rule change moves the auction window.
- Turn off Borders in Settings → Symbol once, or you'll see faint outlines of the original bars showing through.
- Detects F&O names using the symbol on display and identifying if there is an equivalent F&O name for this (e.g., BankNifty <---> BankNifty1!). As a result there could be a few edge cases.
- Ignores F&O symbols themselves.
