Send a cancel signal for a particular order to RobinHood. You will need to retain the buy/sell order url returned from place_order.
Examples
if (FALSE) {
# Login in to your RobinHood account
RH <- RobinHood("username", "password")
# Place an order, should generate an email confirmation
x <- place_order(RH = RH,
symbol = "GE", # Ticker symbol you want to trade
type = "market", # Type of market order
time_in_force = "gfd", # Time period the order is good for (gfd: good for day)
trigger = "immediate", # Trigger or delay order
price = 8.96, # The highest price you are willing to pay
quantity = 1, # Number of shares you want
side = "buy") # buy or sell
# Cancel the order, should also generate an email confirmation
cancel_order(RH, x$cancel_url)
