What did you use for your back testing? Thanks, Louis

Exactly. This fact is well known and is one of the big reasons why this is hard stuff. Multiple systems, risk management, money management, etc are all part of the equation. However, the simple fact remains: use a system that is appropriate for the market. Determining when and how to make the...

I don't have any thoughts about the market per-se, but IMO you need to apply the system that works well in a given market. As you observed, reversal systems are likely having a hard go of it lately because of the strong trends and breakouts. Do what the market is telling you to do: use a...

G-Boa, In FX there is no such thing as "most accurate price". There is only the price offered to you by your market maker. I would suggest you identify who you're going to trade your strategy with and then get data from that market maker. You can achieve a certain level of success with the...

Money management can certainly be automated. Systems are about building an edge and exploiting that edge over time to produce a profit. Money management techniques help you do that by keeping your losses under control. There are various approaches, some of which state that you should increase...

I think it entirely depends on your system and how you have back tested it. For example, some systems are always in the market. Given this type of system you would be selling 200 shares so that you are net short 100 shares. However, there are other systems that would go neutral. Further, many...

OANDA also provides their non-standard box options. http://fxtrade.oanda.com/boxoption/ lrm

You need to make sure you use the Spot or Cash rate, not the USD futures rate. The rate you want is specifically the USD/CAD spot forex rate. I don't use IB, but I would expect if the symbol is USD, then that is USD futures, which would be wrong. Best regards! Louis

John, There is no single price for a currency in the cash market; remember, your run of the mill retail brokerage is actually a market maker. Most of them will typically have a stream of quotes coming in from various banking partners. From this stream of rates they will make the market that...

I use Wealth Lab.

Trade The News (www.tradethenews.com) or Need to Known News (www.needtoknownews.com) provide fast news delivery and (relatively) cheap pricing ($150/month or thereabouts). Best regards, lrm

Look at OANDA. You can trade non-standard lot sizes and can develop against their API. Only drawback is that they charge for their API, but they discount the fee based on your volume. If you trade $6 million round trip USD units the API is free for the month. Best regards, lrm

zentrader, I'm no python expert, but I think something like the following will get you going. Please note, I put periods in instead of spaces for the tabs since the forum would strip the leading spaces. Also, I attached the source file to the message. ---- file = open('c:\somefile.csv'...

newycity, Excel already has a correlation function. Input the time series you are interested in and use CORREL() to find the correlation coefficient. See http://www.ce.memphis.edu/1112/excel/correl.htm for an example. Best regards, lrm

Batman28, Java, early on, was a bit of a beast. It has come a long way. These days you can expect very good performance out of a well written Java application. Most of the available virtual machines will perform Just In Time (JIT) compilation on the Java byte-codes so they can execute...

Batman28, For my trading I use Java. This is because it is the language best supported by my market maker and I want to be able to let my strategies run on Linux. Your decision should really be based (in part) around who you are interfacing with. Remember, a language is nothing more...

Ruby is an interpreted scripting language developed some time ago. It has a very elegant syntax, but until recently it was not widely used outside of Japan (the author is Japanese). A new web framework popped up over the past couple of years called Ruby on Rails. Ruby on Rails takes...

pmsfx, I appreciate your enthusiasm to building a trading system. One thing I would point out is that it is very important to use data from your Forex broker or market maker. There is no central exchange when dealing with the FX market and prices (and spreads!) and vary dramatically from...

I'd be interested. What source is the forex data from? Thanks, lrm
