Example: Cancel all open orders before starting a new position

myApiKeys(XBTUSD) {
    # cancel everything and close existing positions
    cancel(which=all);
    market(position=0);

    # open a long and place a stop 1% below it
    market(position=50%);
    stopOrder(position=0, offset=e1%, trigger=last);
}

Cancels all outstanding open orders (eg, from earlier trades), then closes the position if there was one. Finally, it opens a long using 50% of your balance and adds a stop loss order 1% below.

Example: Place an order in 10 minutes

myApiKeys(XBTUSD) {
    limit(side=buy, amount=99%, offset=10, tag=allIn)
    wait(duration=30m);
    cancel(which=tagged, tag=allIn)
}

Places a limit order, waits 30 minutes, then tries to cancel only the limit order from the first step. If it's not been filled, or only partially filled, it will be cancelled.
