I said I wouldn't do anymore of this but in a way it is a footnote, or summary, to my previous posts on Trading Psyche ... I forgot to add it at the end ....it is quite important.
Since you are a thoughtful type ... underneath it all ... this might help.
Jung is one of the better of the Psyche doctors ... classifying us into types always over simplifies but it has its uses .... as a very basic intro to Jungs typologies .... he said there are four psychic types:
- intuitive (brainstormers, philosophers, dippy hippies)
- thinkers (logicos, nerds)
- feeling (networkers and nice guys, touchy feely)
- doers (action wo/men, jocks,meatheads)
I put the postive aspect and negative aspect in brackets i.e. my homespun version FWIW
Notice that if I am an action man I think feeling people are too touchy feely and squishy (only good for dating).
We are all,'all of the above' ... we are super strength in two (usually) ... we favour one mode, and use it most of the time ... then we have our second favourite that we rely on to a lessor extent (never totally and never for long periods).
If we want to experience life more then we need to learn to use our least favoured fuctions ... this is incredibly hard to do ... if we are an intuitive feeler we will do anything to avoid the gym or nerdy stuff ... it is also pretty hard to self assess our typologies.
In my case it is pretty obvious that I put more effort into avoiding reading the manual or learning math or learning IT than it would take to actually learn some ... even when I know that it is still very hard ... you can see that when I learn math I learn it the intuitive way (lots of graphs and excel etc ) ... my eyes glaze over when I see more than 1 or 2 lines math formulas.
I do better with programming, than math, because it starts with philosophising and then sorting out the psuedo code ... more up my alley than pages of math hieorglyphics.
>From the little bit you have told us you have actively avoided evaluation of your system at a technical level ...in spite of Howards books, many forum discussions, my easy stats website etc you still managed to avoid it ... that should tell you something and indicate that it will be pretty hard for you to actually face up to learning stats, from a technical viewpoint (even if you make a rational decision to do it ?)

>
> Study one metric, or evaluation idea, and ask questions about it and then move onto the next.
>
> - perhaps you are really asking something else ... you seem to be questioning your own tolerance for risk ... there is no objective metric to measure this ... it comes from inside and you are the only one who can see inside yourself.
>
>
> A few reflections on 'tolerance for risk' to get you started:
>
> - for some people it is innate ... I am risk avoiding machine ... it is just in me .. I can instinctively taste, see and smell risk ... I see risk in places you guys can't even imagine.... you can't buy that skill.... just do your best with what you have.
>
> - there are formal risk assessement techniques and processes etc ... I worked in an industry where we ate risk assessments for breakfast ... formally recorded risk using written procedures.... some knowledge of formal techniques might help some .. this knowledge is in my subconsious and coupled with my innate feeling for risk it must help me a good deal.
>
> - I am not a gambler ... it is interesting that our money management strategies were honed by gamblers ... Osborne -> Kelly -> Vince et al and from betting on coin flips (we call that two up in Australia) to betting on a move on the price of Gold.
>
> - 20/30 years ago I went into business for the first time .. I was young and silly but somehow I realized that it involved risk and coping with risk .... this seemed to be something I had to test rather than intellecutalize.
>
> I hate Casinos ... noise, smoke, a fair % or the people are pretty rude, some big drinkers etc ... but I went quite often for a few months .. gave myself a kitty to start with ... the rule was to leave if I lost the kitty ... used a totally dumb methodological approach ... played roulette on the red and the black .. doubled the stake after a loss ... hadn't even read the textbooks about gambling and staking ... know a lot more about the odds now.

> - when money is involved it seems like life and death .. normally nice people argue over a two dollar bet

> - some people are innately bad losers ... kick the table and fight with the staff
> - every one is an expert ... everyone has their pet theory .. they love to talk gambling and especially give you some free coaching
> - some girls liked the excitement and the money (I was approached a few times)
> - newcomers distracted me from the game asking for tips etc ... I must have looked like I knew what I was doing ... I looked pretty serious writing down the trade sequences etc
>
> - no matter how much money is a stake ... the blood pressure goes up .... whether or not you can keep the blood pressure down is a natural skill ... perhaps we can learn to manage it better if it is not our natural bent.

I am a free man, in most ways (spiritually and philosophically etc) ... I have a life outside of trading ... I have goals in my life that are not based around trading ..... trading is a means to an end ... albeit a wonderful trading ground to develop my temperament and skills ... all of this interacts dynamically.

> If you want to learn more about MM etc then Howards book, the forum and other books/sites definitely help ... it has taken me years and I am still not an expert in the subject ... I can talk to anyone about it without embarressment though.
>
> As an aperitif ... a couple of points on metrics, risk and MM:
>
> - there is a theoretical (mathematical) stake for every system and account size (a lot of hours study required to learn this stuff) but there is a corresponding optimal emotional level of risk ... where is your emotional level... really ... not pretend level ... you can't fake it ... figure it out now before going any further.
>
> - your biggest loss to date is not the biggest loss you will ever experience
>
> - the aim of MM is to stay in the game ... we can't win if we have no money left to play with
>
> - the size of the account is very important ... the bigger our account the further we are away from 'isk of ruin' ... in trading $10k is just training fees ... if you lose that much consider it the cost of your training course .... $100K is the minimum stake required to play the game (same as the tables in the casino) ... if we have less than $100k we go to the low rollers tables (options etc ...easy on the margin trading) ... at least $200-300K is needed to even get into the high rollers room.
>
> - if you are ruined do you want to walk away with half of your stake or are you really happy to play hard, play to win and wala away with zero dollars if you are ruined
>
> - if you trade on margin are you really happy to walk away owing the broker money if you are ruined ... maybe have to hold a fire sale to pay your debts?
>
> - looking at your systems, in some cases, you have 0.6 or maybe 0.55 prob of a loss ... six in a row == 0.6^6 ... and you have very high ave losses (trading futures on margin?) ... so far you haven't experienced that kind of losing sequence?

> - I have made some psuedo tickers from random data (say 100 tickers) ... then I optimized a MACrossever system on those stocks ... naturally enough, while the population is break even (if you join all of the psuedo tickers together they add up to a sideways market without significant up and downs in between ... if I look at individual stocks some outperform (the individual samples have variance ... half are up and half are down ... how much up and down depends on the volatility I introduce to the process when I make the psuedo tickers) .... after I optimize if I sort by any metric in most cases the same tickers end up at the top i.e. a large number of AB's builtin metrics are all telling us the same, or similar things .... looking at the exceptions, then looking at the 'correlated' metrics would be one way to start to learn something about metrics ... why are some similar and others different ... I guess we could study the exceptional metrics and either accept or reject them, for our own use ... that would either narrow the field, byu getting rid of some, or turn up something we like.
