Assuming the Large Trade Alert uses the time and sales to look for large trades executed in one trade but given how
icebergs/max show and sniper order algos are used to break up orders as to not send a huge order to the market
it would be a good idea to have an option to trigger the alert based on the values in the pic below as an alternative.
When that value in white > X. would be pretty simple to do.
Please and Thanks!
