according to multiple sites here are the codes:
Post# of 85504
100 I need shares.
200 I need shares badly,but do not take the stock down.
300 Take the price down so I can load shares
400 Keep trading it sideways.
500 Gap the stock. This gap can be either up or down, depending on the direction of the 500 signal.
not sure if any number beyond 500 means anything...
