IB didn't execute my stop, maybe they reinstated rule "last is not last"

I am going to be watching my IB executions very closely

IB stated about 4-5 months ago they have removed 3 requirements for stop to be executed which causes slippage

my stop didn't execute today when LAST TRADED price touched it in YM

Lets hope this is just one freak occurrence and that IB didn't bring back the silliest rules for definition of "LAST" that I have ever seen in this industry

 

check your audit file.

 

ok I found wed audit file, am going through it now

what am I looking for ? if you want to cut down my search

 

all I see in my audit file is that order was placed

 

is it market,limit (if limit-what is the price), is it been accepted,routed to proper exchange? things like that. don't know,if trigger method is in audit file. i'm not familiar with YM(i trade stocks only,with very big stops,which i prefer execute manually). also-call to trading desk, they may give you some explanation. option 2 on 800 number

 

it was a stop order that turns market order, its been routed and everything is fine, except it didn't execute
I won't bother calling IB for this one occurrence,

second time this happens I will give them hell on the phone

I day trade futures so I will soon find out if this was FLUKE or the NORM

 

even IB is allowed mistakes but if this is return of 3 requirements to define LAST TRADED price

there will be hell to pay

 

You shouldn't let this go without an explanation from IB.

Here is what IB says about stop orders:

"Stop orders are triggered when the market trades at or through the stop price (depending upon trigger method, the default for non-NASDAQ listed stock is last price), and then a market order is transmitted to the exchange. "

If IB stop orders aren't working as described IB needs to explain why or fix the problem.

 

Was it touched or traded thru?

 

it shouldnt matter if he has a stop market order, if that price is printed his stop should execute.
