it is a cool market that includes the top 500 stocks of the USA, it fluctuates depends of market evaluations!

The daily price difference is as:

\[ \Delta_t \;=\; C_t \;-\; O_t \]

index
- \(C_t\) is the closing on day \(t\)
- \(O_t\) is the opening on day \(t\)

The absolute daily price difference is

\[ \lvert \Delta_t \rvert \;=\; \bigl\lvert C_t \;-\; O_t \bigr\rvert \]

where
- \(C_t\) is the closing price on day \(t\)
- \(O_t\) is the opening price on day \(t\)

## Global Markets the global markets can influence it due to trade wars that effects the imports and exports of specific companies

today <- df[1, ]
bar_df <- data.frame(
  t  = c("Open","High","Low"),
  v = c(today$Open, today$High, today$Low)
)
ggplot(bar_df, aes(x = t, y = v)) +
  geom_col()
