Quote from themickey:
If as time goes on the markets become more efficient, what does that mean for the trader?
Efficiency meaning that finding a profitable edge becomes more difficult.
Does that mean that as more and more smart brains enter the arena it becomes harder to make a profit?
Will there come a point in time that it will be very difficult to make a profit as faster and smarter scalpers continue to pick off the winning edges.
Does that mean price behaviour will become more random?
Do traders themselves become more efficient, smarter, less naive, more cynical, less trusting, more competitive where we enter a world of dog eat dog until we all die?
I'm a bit concerned about this, Where will it end?
Sorry about all the questions and I wasn't sure where to place this post, I was thinking along the lines of futures trading, but perhaps it can apply to all sorts of trading.
Computers have helped us advance, but also made us more competitive I believe, margins are becoming slimmer even in retail sales due to online access to markets.
Perhaps the people to win the most will be those with the cheapest costs, look at the chinese, but they too are now experiencing inflation, next country might be india and so it goes, on and on.
I'd appreciate your thoughtful inputs.
I only have personal experience from 1957 onward.
In stock trading, the volatility has been about the same. In terms of making money (my standard) the opportunity has shifted in the direction of making the same money in less lengthy intervals. This affects the most important variable in making money: the exponent of the annual compounding formula. I crossover trade high beta repeater type stocks. I use leading indicators of price.
In commodities trading, over the years a lot of new instruments have appeared. There is no quality regulation so a person is very unrestricted in what and how he does things. The major improvement has been to lessen the granularity of all the markets. This means you can move the operating point to increase the exponent much more than you compromise on the size of each profit segment. The greatest advance in commodities is being able to see more and more of the "controllers" strategies. As you would expect I fit into the parasitic, front running technician category. In the last 20 years, I would say that the "take" has about doubled. One nice aspect is the size of the markets. Most markets continue to grow and mature. And there are more and more markets.
The advent of "quants" has been a really nice addendum; the churning effects makes the use of logic a lot "smoother". I use a count down counter; there is no chatter to have to eliminate at this point. In logic, the finite possible solutions are all known. As money is made, logic steers you to the end effect solution that becomes active, then you zoom in to be focused on carving the turns at a multiple of the market's contemporary capacity (this is a harmonics determination).
The future looks unlimited and much better year by year.
Trading costs are trivial. There is no competition. Fortunately, there is a misplaced belief system vis a vis "edges".
The non-edge orientation faces head on both efficiency and effectiveness. The test of performance comes down to two things: trend volatility and trend overlap.
The combination is called: the long diagonal. A cycle of two opposite trends has two long diagonals, one for each half. The market offers; the taking relates to extracting the full offer.
