All that’s showing is for about 15 mins the ask was pretty much the same.
The heikin-ashi are averaging based on the previous which is why you are seeing it step.
So it just went 110 to 115, stayed at that ASK for ~15mins, and then back to 110.
Liquidity and volume are the reasons, on a very liquid stock it might change many times a second, on very illiquid it might be weeks between a new quote.
Swap to normal candle on it and it’ll give a better view of where the ask is in this case.
There’s nothing cut off just the price hasn’t moved much in those candlestick periods and has found either a floor or a ceiling depending on what way you look at it. Great trigger patterns
