Why is there such a divergence between the two indices ? BLS Spot is at double the 2002 lows.

Look - with options, anyone can get lucky once. Being consistent is another thing completely. He was deep ITM and got lucky ... that's all. Let's have him start a blog to see the rest of his trades.

Is anyone tracking the performance of "Fast Money" traders on CNBC ? I think some of them have made some great calls, but fear many of their calls resulted in losses.

Well Guys...thanks for that confirmation. You know tonite's performance was a huge revelation to me.... I've never seen him quite so "shaken up". If 2016 goes the way of the real pundits, his show just may be "OVER" this year.

He was a complete maniac talking at a rate of speed and elevated loudness not witnessed in quite a long time. Wow, he's really got a problem......It's so obvious now.....that ego of his has really gotten to him. Sorry, Jim, IMHO....you really suck. Your big problem: you never go short. And...

Once again, what is the definition of HFT ? Is it based on average P&L ? Based on Time-in-trade ? Trades per day ? Suddenly, you are back to mostly discretionary day trading...where only a very few talented traders succeed. My feeling is that your best approach is a "portfolio" of algo trading...

I always thought about the dangers of having signals and indicators working from one data feed while the orders were placed using a different feed. Can you imagine the signal indicating to buy stop at 40.50 and the IB data indicates 40.80 and you get filled 30 cents from where you expected.

There is really nothing wrong with the Interactive Brokers API for data acquisition except getting price history is tough because they "throttle" it. With IB, you have two options in real time: 1) Real Time Bars 2) Sampled Subscription

Depends. With a strat like that, you MUST use tick or x-minute data for backtesting. Otherwise, daily data will never tell you which came first, the high or the low. Plus, you've gotta have in place at least profit targets.....stop losses may not be needed for that short time frame.

I think you are gonna need some rules for holding some trades overnight into the next day....probably based on the current open position profit or some other measure.

What's the expected ATIT (average time in trade) ?

Only day traders. Longer term traders especially those doing sophisticated options strats will do fine.

Dunno. I look at the world class poker matches and I am just astounded at the intuition exhibited by the best players. I don't see how that can be "programmed".....

Machines are stupid from the standpoint of market economics. If you asked the algos 2 years what would be the direction of the copper market, they would have said "up"....when in fact the exact opposite occurred. Bottomline: Algos best for very short-term technical trading....where supply and...

Cool story if true. Now the "dark money" was from.... 1) drug Lords 2) rich fugitives (like Mark Rich !!) 3) Somalian Pirates Which ??????

This just proves that public education has been and WILL CONTINUE TO BE.....an abysmal institution. We should have created a voucher system where everyone can pick their own private school. Then, there would be true competition and outstanding teachers and facilities. Instead, we are mired in...

Of course....we all know this. Which is why "machine learning" is sometimes a case the dumb teaching the dumber. If you don't have a good market premise to begin with, you're likely just curve-fitting the trades to the price history.

Have you given up on this market or what ? Saw no recent posts and nothing on your website !!

How the heck are you going to make money if you never take a profit ? You should at least employe a trailing stop loss. Again, make the amount based on the volatility. I've heard of good results when tightening the trailing stop amount the higher the open profit becomes. Good backtesting will...

Exactly.... and these seemingly "minor" restrictions actually make a big difference in performance of algos. To be successful in this game, everything has got to be "perfect": 1) a good, non-correlated mix of algos 2) streaming data in the correct bar type 3) excellent risk management 4) a good...
