Quote from fandelem:
how many contracts are you trading at a time, on average?
I trade in around 10-lots, scaling at times - max up to around 50 normally. I have been almost double that one time, though .. but won't do it again for scalping. I think that I might go for spot trading some later day.
Most times I will vary my sizes quite a lot. My position trade is not very big, but with 2 entries.

It all depends on what I perceive the market conditions are. I normally try to let all trades be profitable, and not let them go negative, other than for a possible first entry. Most times I will scale the trade upwards in size then.
