How to tell if your broker hunts stops

Here's an email I received from a signal provider.

Open a real or demo account at Dukascopy http://www.dukascopy.com/
and watch their price feed at the same time you watch the price
feed at your broker, or multiple brokers. At one point I used
to watch 6-7 different price feeds at one time but now only 2-3.
At news time you will see the manipulation the most. The other
brokers will widen spreads, even brokers like FXCM who say they
are now a pass through broker but is not. Unlike a true pass
through broker like Dukascopy won't have their spreads get wide
at news time, it will just be fill or
kill with your order if you try to spike news trade.

WARNING: Most brokers do not hunt stops on demo accounts, so you
must keep watching your live account, but you can compare it
to Dukascopy's demo account becuase they have never hunted my stop.
And no I am not an IB for Dukascopy.

Now here is the interesting point, watch price on all the brokers
as it hits major support and resistance levels and a very
high percentage of time you will see "price" spike on the bad
brokers. That means they are hunting your stops. You will be
shocked how often you will see it, even 5 pips off to me is
not excusable and it should not be to you also. They do
this because they are trading against you and make money every
time you lose. Please don't email me a lot of questions because
I really don't have time to explain it more, just watch lots of
broker's price feeds and you will learn. I already have heat
from many brokers on my bad list and telling the truth now will make
it worse but I am not afraid. I really want to help all you new
traders that did not know what I just explained.

Thanks,
Cindy
