under which id?

I am not that doubtful either. the question is: if he found the holy grail, should he be another james simons?

there is a mark brown who often appears on CNBC, is it the same man?

Mark Brown said he found the holy grail, which is just one page code. if it is so simple, why so few found it and it took so many years for his team to get where it is? does any one have idea what status of his so called holy grail? if it is true, would not he be another renaissance tech...

i think it is the exchange policy of 10 cents spread. the price always sits at 10-cent multiples.

the official spread is 10 cents. why do not use 1 cent as stocks do? the explanation from exchanges is that each stock has an option chain, and they do not have computing power to handle the activity if the smaller spread is allowed. I think that is excuse, since even for qqqq, only the closest...

who is the only consistent winning trading on elite?

the option trading volume is usually low, because it is not suitable for day trading or hft due to the large bid-ask spread. for sina as an example, the bid is 8. and the spread is 8.3, the bid-ask spread is 4%. thus it makes impossible for day traders or scalpers. the question: why does...

it takes a few months to rewrite all programs. besides, I feel secure parking money with IB.

I think the commission of more than 750k to IB is almost net gain to IB since I usually do not hit other's order.

for the last 4 years, I have generated around 750K commissions for IB, which can buy lots of computers.

for example, I submit relative orders at the support/resistance lines, when price goes to that level, I modify price so that i can possibly get the best fills. when closing the position, i constantly adapt the price so that I can close out at the better price. I have to send out orders for each...

IB so far is best for my strategy. I tried other strategies, not so successful.
