yep. on top of that there is not much companies left and the list is getting smaller and smaller everyday. exchanges\banks\etc are trying to mask all this with ridiculous amount of various useless ETF',ETN's whatever,chineese and canadian companies, but we all know the truth. US market is dying...and dying at the pretty fast pace

Quote from ASusilovic:
Nanexâs Eric Scott Hunsader â the guy who likes to dig through trading data to unearth weirdly fascinating algorithmic patterns â is out with quite a chart on Monday:
And no itâs not a new design for a Missoni scarf. Itâs actually a chart tracking the deteriorating market depth in the emini future contract. The red line at the bottom reflecting the most recent data.
Thatâs quite a large drop over the last few months.
Furthermore, Hunsader is adamant itâs nothing to do with the holiday calm period. He believes itâs actually the result of one particularly harsh algo, which he calls âthe disruptorâ:
Take the electronic S&P 500 futures contract, known as the emini, for example. This is, or used to be, a very liquid market. The cumulative size in the 10 levels in the depth of book was often 20,000 contracts on each side. That means a trader could buy or sell 20,000 contracts âinstantlyâ and only move the market 10 ticks or price levels.
Even during the flash crash, when hot potatoes where flying everywhere, the depth would still accommodate an instant sale of 5,000 to 10,000 or more contracts. Not anymore. On Friday, 2,000 contracts would have sliced right through the entire book. Not during a quiet period, or before a news event.
Pretty much any minute of trading that day after the 9:54 slide. And it wasnât just Friday, the trend in the depth of book size has been declining rapidly over the last few week. What used to be the most liquid and active contract in the world, which served as a proxy for the true price of the US stock market for decades, is getting strangled by the speed of light, a weapon wielded by HFT.
Without going into detail at this time, we think we know one cause of the drop in liquidity. A certain HFT algorithm that we affectionately refer to as The Disruptor, will sell (or buy) enough contracts to cause a market disruption. At the same exact time, this algo softens up the market in ETFs such as SPY, IWM, QQQ, DIA and other market index symbols and options on these symbols.
When the disruptor strikes, many professional arbitrageurs who had placed their bids and offers in the emini suddenly find themselves long or short, and when they go to hedge with ETFs or options, find that market soft and sloppy and get poor fills. Naturally, many of these arbitrageurs realize the strategy no longer works, so they no longer post their bids and offers in the emini. Other HFT algos teach the same lesson â bids or offers resting in the book will only become liabilities to those who canât compete on speed. Hence the reduction in liquidity.
So, because people have caught on to the antics of âthe disruptorâ, theyâre reluctant to offer any depth in their emini bids and offers.
Which presumably means âthe disruptorâ will be looking to move on to some other market soon enough.
In the meantime, we suggest itâs at least a good name for the worldâs first high-frequency-trading inspired rollercoaster ride.

Good to know that there is a "DISRUPTOR" out there waiting for your money...
This is false. There is plenty of liquidity in ES. 6 million contracts traded today. The fact that the book is not showing as much, means that market orders are preferred tool (as it always is with big players who want to hide intentions). . Use cumulative delta to spot the market orders trend and divergences, then you will see how liquid this is.
I had three different ES trades today that slipped at least one tick... and one of those positions was a meager four-lot that slipped -1 tick on two and -2 ticks on the other two.
As for TF... that one is pixie dust. Forget about filling anything greater than 1-lot when the algos are blasting.

Those of us who traded thru 2008 versus now can readily see the difference in liquidity. That's why back then the volatile swings would many times make u-turns or 1-2-3 turns in direction. Now everything is total v-turn reversals when the algos strip a ladder one way, turn tail and head the other direction.
I had stop orders in 3 pts below the market... long trades with stops trailed in the afternoon ramps.
That's what we're talking about: "fluid" markets = plenty of open interest on the strikes. There is not open interest on the ladder... all that volume is algo churn playing volley ball with one another.
Just because huge volume churned does not mean it was available to everyone for fills. It was swept up by machines clearing the strikes, unavailable for liquid fills by everyone alike.
Demand for fills thru directional swings exceeded open interest resting in the market. How hard is that concept to grasp?
I thought the site owner, Baron, warned you about this stupidity.
