edge test

Quote from darkhorse:

Decoupling that link is part of what I'm talking about. The stronger your understanding of markets, methods and management, the more permanent your confidence becomes, regardless of short term performance.

If your edge and your stomach are strong enough, a 51% drawdown wouldn't necessarily have to phase you if

a) it's within your normal paramaters of expectation to get clocked once in a while

b) your high volatility system has a demonstrated capability of producing 100%+ returns

and

c) you have a large enough trading account that a 50% drawdown would neither crimp your lifestyle nor hamper your ability to trade in any way, giving you full confidence that there's plenty of time and resources to come back strong.


That may well be, however, I think that if a trading method experiences a 51% drawdown that the upbeat trader may have misplaced confidence issues. Whatever the historical performance of a strategy may be, you cannot hope to finesse it too finely with statistics. At best, statistics is a blunt instrument when trying to predict the future based on the past. Whatever the historical performance or testing may have shown, assuming that a 51% drawdown can ever be "acceptable" is tantamount to playing chicken with the trading gods.
 
Quote from darkhorse:

Surfer's mentor thread has inspired me to offer an observation of my own:

If you doubt your edge, you don't have one. Your doubt represents a low quality approach, a lack of understanding re market mechanics, or both. Even if you have a valid mechanical system, adding doubt to the mix invalidates the crucial psychological component of the system.

To frame it in terms of alcoholism: "if you think you might have a drinking problem, you do."

Which in this case would translate to, "if you think you might not have an edge, you don't."

While great traders deal with uncertainty every day, they have supreme confidence in their mental structures and their trading heuristics. Even quant traders who continuously discard one strategy for the next have a testing and evaluation methodology that they can place full confidence in. They don't wake up feeling like they have to reinvent the wheel every month.

I think a graveyard for many traders is their willingness to stay in the ether of muddled confidence for years and years, never taking the time to really get a bone deep level of understanding when it comes to market mechanics and human observations.

p.s. hi everyone my name is darkhorse and I have an ET problem...

This pretty much goes along with what I have always told people. Your only real edge is the confidence that you have one, because if you dont have that your edge is gone.

However, unless the edge is legitimate, the confidence is misplaced. (Are we talking in circles? :) )
 
Quote from darkhorse:

I think, in a sense, that I am disagreeing with a core belief that is often presented on ET. A real edge shouldn't be waxing and waning all the time. It should be solid.

WDGann once said his 'mojo' waxed and waned during the day. This led to a variation in his confidence level. However, since he trades mechanical systems, so he has said, I doubt his edge is much affected by this. jmo.

If your logic holds, then would the opposite necessarily be true? "If you think you have an edge, then you do."

For me it would be true, but then, I try to be honest with myself. One problem I have with an established edge is thinking it is always present and available for use in trading. Others here have said there are lots of edges in the market, they can't all work all the time. One poster said that he uses an 'ambush' type of trading...waiting for a specific type of trading setup, his edge, and then trading it. That has been for me, a very sharp observation.

No... there are many propositions that don't work in reverse.

Consider the alcoholic statement: if you think you might have a drinking problem, you do.

The opposite statement, "if you don't think you have a drinking problem, you don't," is not necessarily true. There are plenty of alcoholics in denial (just as there are many traders in denial).

Ultimately, "edge" has to be defined by some measurable criteria in the real world.

Or to put it another way, if you were accused of having an edge in court, how would the prosecution prove their case. Saying that you do is not evidence that you actually do, only that you might be delusional.

Not necessarily.

There are private traders who are comfortable with an almost blistering degree of "heat" in their portfolios, to borrow an Ed Seykota term. Seykota himself is one of them.

Let's say you have a five million dollar trading account, and you trade in such a way that you have a 40% annual return expectation over time. Year to year, your annual returns range from +300% to -60%.

Now, if you are down 60% on 50K or 100K, that's trouble. But if you're down 60% on 5 million, you still have 2 million- plenty to readjust your risk percentage and continue to trade with proper contract granularity.

Let's further assume that you have an extra 5 million stashed in safe haven areas, as a backup in case you hit a freak air pocket that is out of line with your worst case scenario.

In this situation, where the trader has more than enough capital to continue operations no matter what, and where he has calculated the odds and is willing to accept occasional 60% drawdowns alongside 300% returns to pursue a 40% long term expectation, there is nothing wrong with being down 51% from time to time. Assuming the trader has an iron stomach lining of course.

I think it's quite possible to be confident and grounded in your edge yet still experience emotional swings. The short term and long term elements operate on different levels.

Kind of like knowing you love your wife no matter what, even when she makes you want to beat your head against the wall...
 
Oh sure, absolutely. And if you think of your wife as a source of strength then beating your head against the wall shouldn't hurt. Thanks for this interesting discussion.
