For you guys who scalp, are you placing the orders ahead of time? Since if you use a market order you get a terrible fill, it's better to stick your order out there true?
Whatever you choose to scalp (I wouldn’t personally recommend it but I’m biased and freely admit it) - you MUST have a very intimate knowledge of how orders are filled. In futures, for example, is your particular instrument FIFO or Pro-Rata algorithm? If it’s Pro-Rata, is there a FIFO component that gets filled first in the order queue ? If so, how many?
If you choose to scalp, how fast is your ECN? Are you routing orders first through an IB then an FCM and then to the exchange? Are you trading a product where professional trading firms collocate servers at the exchange? Are you trading a product where professional trading firms pay for order flow?
If I look at a firm like Jump Trading - they are literally paying hundreds of thousands of dollars per month on ECN infrastructure. And if YOU are legitimately “scalping” the market in the true sense of the word, you are competing against them and dozens of other well capitalized firms like them.
I wish you good fortune in your endeavors.
