Vince’s Leverage Space Model: better than MPT?

March 22nd, 2010 · 33 Comments · Backtest, Money Management

Ralph Vince‘s book Handbook of Portfolio Mathematics has been shamefully lying untouched on my desk for a few months… I started reading it but never finished it. I recently found a 30-page paper introducing the ideas and principles of his Leverage Space Model. I thought reading it might be a good way to get back […]

Were the Turtles just lucky?…

March 8th, 2010 · 23 Comments · Strategies, Trend Following

  Most people will have heard of the mythical Turle Traders, a group of novice traders set up and mentored by legendary “Prince of the Pit” Richard Dennis. Dennis did so to set up an old argument with fellow trader Bill Eckhardt on whether trading could be taught or not (not unlike the story in […]

February 4th, 2010 · 2 Comments · Backtest

This post is trying to present a process to determine your bliss function, as a follow-up to the previous post introducing the bliss function concept. We’ve seen that the bliss function is not a universal function but needs to encapsulate your own criteria for evaluating a trading system. Similarly to popular dishes, everybody has got […]

Amibroker V. TradersStudio: Speed comparison Fight

November 10th, 2009 · 2 Comments · Backtest, Software

It might not capture the imagination as much as the recent Haye v. Valuev WBA World Heavyweight Championship fight (it probably might for some of you… ;-) but I decided to organise my own “fight”: AmiBroker V. TradersStudio! And similarly to the boxing, speed was of the essence – with one platform completely out-performing the […]

Amibroker e-ratio code

November 9th, 2009 · 32 Comments · Code, Development, Software

I recently posted about the e-ratio as a tool to measure parts of a trading system (the code files to compute the e-ratio in TradersStudio and Excel are also available). The e-ratio is supposed to be a quick tool to check how signals might add some edge to a trading system. However computing the e-ratio […]

How can Walk-Forward testing keep your system a step ahead?

November 5th, 2009 · 17 Comments · Backtest, Software

Out-of-Sample testing is a necessary practice to avoid curve-fitting during the optimisation of a trading system. Walk-Forward testing improves on the idea of out-of-sample data testing and is designed as an on-going, adaptive approach. Its invention is mostly credited to Robert Pardo (read more about it in his book) The way it works is fairly […]
