Experienced trader feedback wanted - doubling positions when in a loss

Quote from silvermotion:

with the swings we had last week i believe everybody and their dog made money

My system works best when the market is swinging but not in the extreme way. As to the notion that everybody made money last week: I know I did. :D :D :D

Some info behind it had been disclosed on the ES J thread. Do a search and you shall receive. :D :D
 
Quote from Kevin Schmit:

Martingale betting methods can be useful, can overcome
a small negative expectation or expand a positive expectation,
when the return series being traded is antipersistent, mean
reverting, or has a variance ratio less than one. Stock index
return series at the interday time frame have, for the past few
years, had precisely those characteristics.

Intraday trading markets are a pretty poor pseudo-random
number generator and such return series fail most of Knuth's
standard tests.

The first two random number generators shipped with WinCraps
could be beaten by a number of martingale betting schemes.
Interestingly, these RNG's failed the same randomness tests
that intraday market return series do.

The trader in question may have a small positive expectation
going in due to his "Murray Math" trading method. Even with
a zero edge, martingale system "Oscar's Grind" against even
a slightly antipersistent series, has, given a sufficiently large
initial bankroll, been shown to be a recurrent Markov chain --
meaing you won't blow out trading it!

Is that really true if we take S&P 500 data? I can't imagine any martingdale strategy that would not have gone bust during the 87 crash, unless one is trading ridiculously small on the initial bet size, in which case returns during all other periods will be mediocre.
 
Quote from scorpion:

doubling on losing trades is stupidity period. managing risk is what trading is all about , smart trading is trying to put the odds in your favor, doubling on losing trades is pure gambling which should be done in a casino. no real trader will call it trading imo.

I have to agree with the majority here who contend that doubling down per se is pure insanity. However, this post raises an interesting question ...

After a series of breaches through consecutive support or resistance levels, do odds favoring a significant (profitable) reversal increase or decrease?
 
I sometimes hope that market will go against me (my position) so I could get a better price.

For Example:

My full position is 5 contracts.

based on charts I think that market will go down. So I enter short 1 contract on a first weakness. (even though risk reword is bad but I do not want to miss a move to the down side when and if it will happen). Should the market get to my desired resistance I will add another 4 contracts with a stop loss on all 5 contracts.

I do not add based on how many points market moved against me.

Is this considered double down or money management?
 
Balda,

As long as you don't go over your intended car size AND stop price I would not call it averaging down.

Interesting question. I have been simming an approach like that using S/R levels I have derived myself and trading with a directional bias. I start with one ES and double at each level (which could be ten points apart). At the end of the day I look at the maximum loss at each level as my size increases. Using a .05 loss amount for my funding needs It has been as high as $300k to maintain a loss of only 5% on the trade. The average seems to be in the $50-100k most days. So the bottom line for this would be can you stand the big hit when the loss in a position exceeds the 5% loss on any one trade?
 
One of the biggest reasons for trader failures, or blowing up, is adding to losing positions. That being said, let's chat for a second.

I have played hundreds of hours of a modified Martingale system with a (nearly) 50/50 game (Baccarrat), and if we take into consideration getting our costly comp's (trips, rooms, shows, etc.), we can "justify" the overall negative expectation to a point.
Without the fringe benefits, and more importantly, when dealing with something like the market which is not a "50/50" game, it makes no sense IMO.

The reason for adding or taking off a position has to be based on what the market is doing...as traders, we are responding to market conditions, and putting on postiions based on these conditions.

To simply "double down" is not even a valid premise in the market IMO.

If, for example, you're trading E's, you're long at 1480, and it breaks a support level, are you not better off closing and possibly reverrsing the postion vs. adding to the losing trade? We have to take into considration things like the VIX, recent movements, Premium/Discount to Fair Value, etc.

New traders would more often than not be better off closing a postion vs. adding to the losers IMO.

Treat each entry / exit as it's own event, based on the overall reading of the market.

(I could go on and on, but I'll spare you guys, LOL... just an overview from my perch).
