It is possible to put orders in between the spread.
Just wait a couple of days and this should be back to normalish trading.
Today a number of people need to call their brokers to make an order.
Nothing to worry about.
It's hard to say if a market maker is involved.
If you are looking for messing around, look for double orders.
Let's say you put an order in to buy 5,000 shares at $0.40
However, on the ticker tape, you see a trade for 5,000 shares at $0.38 and then an immediate trade for $0.40 and you got a fill for $0.40
In that case, you got screwed.
Don't worry though, it's usually smaller brokers that pull this stunt.
This is why I stay away from some of the smaller brokers. They may offer low commissions ... but then they skim your order.
eTrade doesn't really pull this as much as others.
I don't see the trades so, can not tell you either way.
