I Hired a Contract Coder

You’re a trader with serious ambitions to use algorithmic methods. You already have an idea to be converted to an algorithm. The problem: You do not know to read or write code. So you hire a contract coder. A guy who’s paid for delivering a script that you can drop in your MT4, Ninja, TradeStation, or Zorro platform. Congratulations, now you’re an algorithmic trader. Just start the script and wait for the money to roll in. – Does this really work? Answer: it depends. Continue reading “I Hired a Contract Coder”

Is “Scalping” Irrational?

Clients often ask for strategies that trade on very short time frames. Some are possibly inspired by “I just made $2000 in 5 minutes” stories on trader forums. Others have heard of High Frequency Trading: the higher the frequency, the better must be the trading! The Zorro developers had been pestered for years until they finally implemented tick histories and millisecond time frames. Totally useless features? Or has short term algo trading indeed some quantifiable advantages? An experiment for looking into that matter produced a surprising result. Continue reading “Is “Scalping” Irrational?”

Hacker’s Tools

For performing our financial hacking experiments (and for earning the financial fruits of our labor) we need some software machinery for research, testing, training, and live trading financial algorithms. No existing software platform today is really up to all those tasks. So you have no choice but to put together your system from different software packages. Fortunately, two are normally sufficient. I’ll use Zorro and R for most articles on this blog, but will also occasionally look into other tools. Continue reading “Hacker’s Tools”

Boosting Strategies with MMI

We will now repeat our experiment with the 900 trend trading strategies, but this time with trades filtered by the Market Meanness Index. In our first experiment we found many profitable strategies, some even with high profit factors, but none of them passed White’s Reality Check. So they all would probably fail in real trading in spite of their great results in the backtest. This time we hope that the MMI improves most systems by filtering out trades in non-trending market situations. Continue reading “Boosting Strategies with MMI”

The Market Meanness Index

This indicator can improve – sometimes even double – the profit expectancy of trend following systems. The Market Meanness Index tells whether the market is currently moving in or out of a “trending” regime. It can this way prevent losses by false signals of trend indicators. It is a purely statistical algorithm and not based on volatility, trends, or cycles of the price curve. Continue reading “The Market Meanness Index”

Seventeen Trade Methods That I Don’t Really Understand

When I started with technical trading, I felt like entering the medieval alchemist scene. A multitude of bizarre trade methods and hundreds of technical indicators and lucky candle patterns promised glimpses into the future, if only of financial assets. I wondered – if a single one of them would really work, why would you need all the rest? And how can you foretell tomorrow’s price by drawing circles, angles, bats or butterflies on a chart? Continue reading “Seventeen Trade Methods That I Don’t Really Understand”

White’s Reality Check

This is the third part of the Trend Experiment article series. We now want to evaluate if the positive results from the 900 tested trend following strategies are for real, or just caused by Data Mining Bias. But what is Data Mining Bias, after all? And what is this ominous White’s Reality Check? Continue reading “White’s Reality Check”

The Trend Experiment

This is the second part of the trend experiment article series, involving 900 systems and 10 different “smoothing” or “low-lag” indicators for finding out if trend really exists and can be exploited by a simple algorithmic system. When you do such an experiment, you have normally some expectations about the outcome, such as: Continue reading “The Trend Experiment”

Trend Indicators

The most common trade method is dubbed ‘going with the trend‘. While it’s not completely clear how one can go with the trend without knowing it beforehand, most traders believe that ‘trend’ exists and can be exploited. ‘Trend’ is supposed to manifest itself in price curves as a sort of momentum or inertia that continues a price movement once it started. This inertia effect does not appear in random walk curves. Continue reading “Trend Indicators”

Money and How to Get It

Contrary to popular belief, money is no material good. It is created out of nothing by banks lending it. Therefore, for each newly created lot of money there’s the same amount of debt. You’re destroying the money by repaying your credits. Since this requires a higher sum due to interest and compound interest, and since money is also permanently withdrawn from circulation by hoarding, the entire money supply must constantly grow. It must never shrink. If it still does, as in the 1930 economic crisis, loan defaults, bank crashes and bankruptcies are the result. The monetary system is therefore a classic Ponzi scheme.
