Not sure I understand the question, but in a flat vol world, calls would be priced higher than puts because of positive interest rates. Calls increase in value with interest rates, puts decrease in value with interest rates. Of course in the real world, vol is not flat and put vols tend...

For the benefit of all, a Broker executes your trades a Prime Broker, usually, clears your trades usually you have several Executing Brokers who all give up their trades to be cleared by the Prime. This is just so that you have records at one place. All that other stuff (free...

On Capital Introduction Let's face reality here. If you have $1MM in your fund and say you prime with Goldman, I don't think you are going to get much capital introduction attention. A salesperson is not motivated to try and turn you into the next $1bn fund - that's an unlikely event and not...

is accurate. H2O - please don't give tax advice without thoroughly checking it.

agreed, i personally know people who used to do it part time with a few hundred K and now manage tens of MM. It can be done - if you are good. Getting to 100MM+ is an entirely different ball game though, imho, for reasons of strategy capacity, ability to build a team of talent...

ktm, I'll defer to you on that. performance should and does attract funds, as does promotion and access. I do see a number of funds on iasg with good track records but with AUMs that are not commensurate. So, no doubt good numbers will bring in funds, but perhaps getting the word out is...

a hedge fund is an unregistered vehicle for pooling a great deal of other people's money together to pursue trading/investing strategies. no other vehicle is as well suited to this purpose, with the exception of the mutual fund, which is registered, and an even mightier asset gathering...

Any good experiences with other automation platforms? I am using tradestation. maybe I am overly paranoid, but is your code accessible by TRAD?

Wondering if anyone has automated trading through Excel? Would you recommend it?

That's probably true ... but most people will be unable to trade most of them. Most systems severely test your manhood at some point and true grit is in short supply.

my point exactly - when spreads narrow because of many players, leverage becomes more important - hence profitablity becomes more sensitive to interest rates also, it is a dangerous short vol situation - periodically 3 sigmas are going to come along and wipe out the less diversified and...

I also thought merger arb was commoditized, but maybe someone with more experience can comment. The trouble is that merger arb people will never tell you that their business sucks. But actually I don't think that merger arb will ever go away because mergers will never approach 100% certainty...

how do you find trading conditions in SG? hours? tax? support? services?

EricP, Thanks for your contributions - this is very nicely done. Question : you mentioned testing for profit confidence as follows [ p * n ^0.5 ] / sigma where p = net profit per trade n = # of trades sigma = std dev per trade we can factor out n so, it's basically [...

I presume this is for moves that take place over several days? Time frames under a day are distorted by the uneven density of trades during the day, no?

Bdixon - I haven't really read up about efficiency measures so unfortunately I can't point you any further. My interest in efficency is to free up time otherwise spent in random expectancy trades - which allows you to try to fit other trade ideas into the freed up time, thereby improving your...

As an aside, I am in the middle of some extensive backtesting and have began using profit factors. Something I noticed about the impact of filters on profit factors. I started with a system with the following characteristics # trades 230 profit factor 1.12 net income 95 when I...

How anyone can possibly mention marc rich, soros, cohen et al within the context of daytrading is silly. They have nothing to do with day trading as is usually understood in ET.

I've encountered this issue as well - systems designed to capture a phenomenon in one market sometimes doesn't work in another (and I don't mean trend following). I think it is legitimate - a lot has to do with the behaviour of market participants. when do mutual fund pms usually call in...
