here is one wow verb
assign =: 4 : '(x) =: y'
stocklist =: 'DAL';'UAL' (NB. can do in console. later edit variable to
increase stocks). Can be used to add headers/titles too.
stocklist assign each quote each stocklist NB. only have to edit stocklist
once, and you will get new variable names.
DAL NB. assigned in previous statement
maybe a bit too much, but:
". each stocklist NB. will "run" the names of the variables previously assigned
(stocklist ,each 'd') assign each ([: |. }.)@: ". each stocklist NB. assigns
DALd and UALd
UALd
# UAL
2022
# UALd
2021
Prices=: [: ". &> 4&{"1
plot Prices UALd
plot Prices DALd
MaxPrice=: >./ @: Prices
MaxPrice each ". each stocklist
┌─────┬─────┐
│32.84│51.49│
└─────┴─────┘
stocklist,. MaxPrice each ". each stocklist NB. prettier display and
showing which ticker is which price
could reuse trick above:
(stocklist ,each 'p') assign each Prices@:". each stocklist ,each 'd' NB. UALp
and DALp are assigned
plot each ". each stocklist ,each 'p' NB. would repeat above 2 plots, and
simpler below (but this line works for any number of items in stocklist)
plot each UALp ; DALp
The wow punchline is that only stocklist need be changed to get specific whole
new variables, and stocklist can be very long.
