Hey, @Dougal1984. We currently do not have plans to offer charting on more than one type of quotes or display the bid/ask quotes.
While at the end of the day, it’s a business decision to follow the industry norm and adopt LTP quotes for charting, here are some of the reasons why it is specifically helpful for extended hours charting:
- As LTP reflects actual trades being made on the market, it more accurately shows premarket activity at a time when liquidity is considerably lower than usual.
- As mentioned, market conditions worsen during extended hours, and Bid/Ask spreads can widen significantly. This can distort the chart and make it more difficult to interpret.
- When it comes to trading and technical analysis, LTP charts provide more reliable support and resistance levels because they are based on actual trades rather than bid and ask prices, which are dictated by market makers.
- As Bid/Ask spread can widen significantly (for example, Bid - $80 and Ask - $100), LTP shows you more precisely the market sentiment at the time (for example, a trade done at $95).
