Question: "Andy, how much volume do I need to trade
without the risk of really bad fills?"
Andy:
Without having the details about your trading, I will not be in
a position to give you a concrete answer. It depend on the following
factors:
- How
many contracts are you trading? Are you trading 2 contracts or 20,
or even 100, and in what market? Trading the bonds with 100 contracts
shouldn’t be a problem, but you would have a hard time trading
even 20 contracts in the E-mini Russell 2000.
- Are
you a long- or short-term trader? When you trade short-term, even
slippage of one tick can make the difference between winning or
losing. If you trade long term, slippage of a few ticks should not
make much of a difference.
- What
markets are you trading? Trading the meats with a volume of over
1,000/day should be ok for every position trader. Trading the Eurodollars
gets difficult with a volume below 5,000/day.
- Are
you trading open outcry or electronic markets? When trading electronic
markets, you can check the bid and ask on your trading platform,
and you can see what fill you can expect. You can also see if there
is enough volume at the moment you want to enter (bid/ask volume).
You can also see the bid and ask of the open outcry markets, but
most of the time this information is worthless because you cannot believe
what you see. The only way to find out the bid and ask in any open
outcry market is to call your broker.
To
find out if the market fits with your trading style, talk to your
broker. He should be experienced enough to give you some information
about the market you want to trade. Also, test the market with a
few contracts to see what fills you can expect. Then increase the
number of contracts step by step as you feel comfortable.
