# Depth of Market (Level II Ladder)

* requires dom.cfg file with a symbol and dynamic indicator settings:

* to trade, check 'Arm'.
** left-click in yellow buy/sell column.  no more than one column at once, else IB complains about being both sides of market
** right-click to cancel.  
* currently need to watch IB for order confirmation and p/l - next step is on-dom p/l
