The data is in the following format:
I understand that the time value represents the current minute of the day, market open being 570 and close 960
I also assume that volume means that in the 650th minute of market trading 700 shares of this stock were traded
But I am confused about what high/low and open/last mean?
from my understanding last is the last price the stock was traded at during the previous minute of market activity, open is the price its traded at the very beginning of the current minute and high and low are the highest and lowest prices the stock was traded at any moment within that minute.
The above explanation is the most logical reasoning I can think of for this type of data.
Can anybody who has experience working with intraday ticker data please confirm or correct my reasoning.
