Allocation is about how much risk you want to allocate to. This results in the long and complex 'spaghetti code' that is typical for MT4 EAs. This is merely an example, and one which is very easy to code. After a good run, he now has two hundred dollars in chips in front of.

In case you reside on the other side of the Pond from me, you may take issue with my choice of date format. The initial learning curve may be a little steep, but few things worthwhile are easy.

Variables are declared by assigning a value to them, and language blocks are defined by indentation, as in Python. Trading Approach Validation.

In Python, just like in most other programming languages, a single equal sign is used to assign a value, while double equal signs are used for comparison. After that, we start a loop, iterating through all those numbers, just like we did earlier in this chapter. A dictionary on the other hand uses curly braces.

This is a subject which I recommend that you dig into deeper, but also a subject which would take up too much of this book if I go into too much details. This book will go into details on how you can use Python to set up such a backtesting environment and how to write code to test historical performance. You could approach this in two ways, which will probably yield the same information in the end. And trust me, this is not complex stuff.

That we can simply take a time series, get a rolling window and do math on this directly. Some Assembly Required. The first way is fairly straight forward. Once you have executed a code in one cell, you can refer to variables from that in other cells. They make life in Python Land easier, as well as quicker.
