You are welcome. I am in a similar situation as you are - so I get a lot out of threads like this. I too have a system / platform that I would like to see used in a professional setting (in a hedge fund) some time. But I have taken the route of trading my own capital first. BTW - I...

I suggest you make a piece of paper describing the following: 1. Your investment universe - the currency pairs you trade, how you trade them, your target dollar amount exposure. 2. Your assumptions - what trading costs and interest rates you assume. 3. Your backtested performance year for...

You situation is akin to a startup company asking for capital: The earlier you get foreign capital - the more you will be paying for it in terms of lost ownership, lost influence, time spent getting the capital etc. How much time did you spend on building this? Had you spend that time in a...

I use the sharpe ratio of the running total net liquidation value of my portfolio. The profit ratio may hide the volatility of the return in some cases. What is your average holding period? Are you only asking for 20k usd? (I would think it would be possible for you to raise this...

You need a live track record. If you have companies or clients offering you to trade their money on a system that is only validated on historical backtesting they simply do not know what they are doing. These are not the people you should be looking for. Having said that: I think you...

Hey - hire IB programmers at 20 USD per hour - and resell them to John McCain for picking lettuce at 50 USD per hour - huge arbitrage possibility - why didn't I see this before?

It depends on the fitness landscape. Genetic algorithms works because the algorithm has elements of hill-climbing in it. So for it to work the fitness landscape has to have "hills" in it. For complete general problems genetic algorithms are not faster than random search.

BTW: I second tums and edbar's good advice: Take a throughout look at what is out in terms of standard software / platforms before you endeavor on building your own. The more you can get away with using standard software the better. Software development is one giant disgression when the...

"I would not mind to get some side work from this site but that fee worries me ..." If you are placed in NYC I would think it would be hard-pressed taking jobs thru that site with the rates offered. 10-20 USD pr. hour - surely you can find something better in NYC?

Search this forum for similar discussions. You need to spec out requirements and overall software architecture (what broker you have, with what and how you integrate with the outside server etc.) to find the scale of the project and give you an idea of what sort of programmer you need to hire.

I think people have more trust in limit orders and value their transparency - they fear that they may be cheated in some situations with a market order. This may be irrational. I certainly found that my system gets adequate prices and fills with market orders - having said that - my system...

I use market orders; but my average holding period of 1 week is probably bigger than yours. I think I depends on what you are trading and on what exchange. In highly liquid stocks (i.e. AAPL or SPY) you get very low spread cost (something like 0.05%).

This subject pops up from time to time - you need to trust the people you work with - including your programmer. What I don't get is this: How do you know your strategy works? Did you backtest it? If you did backtest - then how come you cannot program it yourself using trade station or...

Sure you can do it. And probably in trade station too. This is not far from what I do with IB and some Java. There are some practicalities involved with a completely unsupervised setup - but they can all be solved.

Why bother with the demo data quality? It is clearly rubbish - designed to be a demo. You need a proper account to get proper data. Obviously. Since most financial data is not free.

I think I completely misread the question. Sorry.

You can use a combination of Yahoo's split / dividend data and opentick's intraday data. The data quality will be reasonable and it is free.

Thanks dsplaisted - so the Open Tick data is not wrong - it just does not have data from all of Nasdaq? If I summerise over a full day - i.e. 2008-04-08 (see the attached xls-file for the actual data) - I get: 36,224,800 From Google Finance...

Hi there. What accounts for the difference in volume data between Interactive Brokers and Open Tick? For example for Apple I get: Interactive brokers: 2008-04-09 09:00 152.05 50448.0 2008-04-09 10:00 152.75 56523.0 2008-04-09 11:00 150.74 39637.0 2008-04-09 12:00 150.85 31612.0...

A question in my naivete: A what timescale would something like interactive brokers scale out? Wrt. bid/ask spread - one simple way around this is to use limit orders which may make your backtesting somewhat more complicated. My experience with market orders is that the price I get...
