Hi Temjin,
I can only venture a guess that you are talking about full automation of the strategy,order entry included, as you have previously alluded to in other posts.
If I'm right, may I ask how you've managed to deal with things like broker isssues, lengthy blackouts, internet problems etc? What happens if your broker's platform goes down just before a major announcement comes out and you're asleep with a position on?? Have you had these kinds of problems before, and if you have, how do you deal with them?
Great questions there frink.
If you referred to my other posts, I am still in the development stages.
You are right that those are very legitimate risks and I have developed, or rather, have thought of strategies to mitigate them.
broker isssues - This remain one of my biggest risk. I am essentially relying on their uptime and connectivity reliability to execute my system properly. This is mitigated by regularly monitoring of the system, set maximum portfolio risk (no more than 10 positions at once, or no more than 5 long/short, etc) and reduce reliance on trading system's rule to liquidate trade. (i.e. have trailing stop / profit targets already set on broker's server)
Another major concern is how the broker manage their client's fund. What do they do with the funds? How risky is it? Do they have plans to shield themselve from the current or future credit crisis? etc, etc.
lengthy blackouts, internet problems - This is less of a problem as I will be using a virtual dedicated (or shared as minimum) server hosted by a professional company with connections located near my broker's own routing servers. I will rather pay for the cost for the service of having advanced hardware security, reliable backup power source, minimum internet access downtime and regular data backup than using my own home desktop computer with unreliable power supply and internet. I would be able to access my hired server through remote access from my home computer/laptop.
just before a major announcement comes out - As I will be desiging intraday trading system with no overnight positions, and that the markets I am trading in is highly liquid, major annoucement that produce major price shock should not present a major problem to me. (in theory anyway, who knows what will happen in the future) I would further mitigate it by the same max portfolio heat strategy and having a balance of long/short.
I am fully aware of the fact that alot of quantitative hedge funds recently had experienced major drawdown when both of their LONG and SHORT positions went against them all at the same time. I don't know if, or how this would happen to me, but the best defense against it would be to limit my positions opened and total % of equity risked.
That's how I would deal with them. I'm sure most of the more "professional" quantitative hedge funds have better strategies to deal with these.
nizar said:Well I beg to differ from Curtis Faith. I've learnt a hell of a lot through internet forums. Alot of the posters (in every forum) are newbies or amateurs or bullmarket champions. But the are a few people who really know their stuff and are willing to share their knowledge and for me that makes the time Iv spent through these forums very much worth it.
Maybe it's my biases toward these forums, there would be alot more newbies and losing traders than winning traders. If I was a winning trader who have been making profit consistently over the past several years, I would NOT even consider making posts in those forum because I already have my own trusted system.
But it's still a good idea to learn what strategies other are using. I stilll believe that some people could potentially develop a great entry strategy but doesn't have other elements in place to make a profitable system. (i.e. exit strategy, position sizing, discipline etc) So yeah, steal their ideas (as long as you are confident in using it) and make them yours.
