Signaal of niet? - I

Welkom bij het hoofdstuk over signalen! Een signaal is een interactie van marktdata met indicatoren, of indicatoren onderling, die je vertelt of je mogelijk een asset wilt kopen of verkopen. Signalen kunnen om allerlei redenen worden geactiveerd. Zo kan een signaal worden geactiveerd wanneer een voortschrijdend gemiddelde met een kortere terugkijkperiode van kleiner dan naar groter dan een voortschrijdend gemiddelde met een langere terugkijkperiode gaat. Een ander signaal kan ontstaan wanneer een oscillator van boven een bepaalde grenswaarde (bijvoorbeeld 20) naar eronder gaat, enzovoort.

In dit hoofdstuk zie je verschillende manieren waarop indicatoren met elkaar samenwerken. Je richt je op de strategie die je in het vorige hoofdstuk hebt ontwikkeld (strategy.st). Om het simpel te houden, haal je alle RSI-indicatoren weg en blijf je bij de DVO-indicator (David Varadi's Oscillator) die je aan het einde van Hoofdstuk 3 hebt geïmplementeerd.

In this chapter, you will learn the definition of trading, the philosophies of trading, and the pitfalls that exist in trading. This chapter covers both momentum and oscillation trading, along with some phrases to identify these types of philosophies. You will learn about overfitting and how to avoid it, obtaining and plotting financial data, and using a well-known indicator in trading.

Before building a strategy, the quantstrat package requires you to initialize some settings. In this chapter you will learn how this is done. You will cover a series of functions that deal with initializing a time zone, currency, the instruments you'll be working with, along with quantstrat's various frameworks that will allow it to perform analytics. Once this is done, you will have the knowledge to set up a quantstrat initialization file, and know how to change it.

Indicators are crucial for your trading strategy. They are transformations of market data that allow a clearer understanding of its overall behavior, usually in exchange for lagging the market behavior. Here, you will be working with both trend types of indicators as well as oscillation indicators. You will also learn how to use pre-programmed indicators available in other libraries as well as implement one of your own.

When constructing a quantstrat strategy, you want to see how the market interacts with indicators and how indicators interact with each other. In this chapter you'll learn how indicators can generate signals in quantstrat. Signals are interactions of market data with indicators, or indicators with other indicators. There are four types of signals in quantstrat: sigComparison, sigCrossover, sigThreshold, and sigFormula. By the end of this chapter, you'll know all about these signals, what they do, and how to use them.

In this chapter, you'll learn how to shape your trading transaction once you decide to execute on a signal. This chapter will cover a basic primer on rules, and how to enter and exit positions. You'll also learn how to send inputs to order-sizing functions. By the end of this chapter, you'll learn the gist of how rules function, and where you can continue learning about them.

After a quantstrat strategy has been constructed, it's vital to know how to actually analyze the strategy's performance. This chapter details just that. You will learn how to read vital trade statistics, and view the performance of your trading strategy over time. You will also learn how to get a reward to risk ratio called the Sharpe ratio in two different ways. This is the last chapter.
