How we can use adjusted price in combination with price limit in stock market? suppose that we have a price limit in a stock market. For example if yesterday last price is
X, today price range for training is
X+a%. We don't have any problem when we are using non-adjusted prices but when we use adjusted prices (as a time series) and using below formula (for example for today open price):
today_open_price_change = (P(today_open_price)-P(yesterday_close_price)/P(yesterday_close_price)
In a time series we have values bigger than
a% (price limit percentage). How we should adjust this percentage (
a%) for adjusted price time series?
