In this chapter, we highlighted how important backtesting is. We talked about two sorts of backtesters: a for-loop backtester, and an event-based backtester. We showed the two main differences and we implemented an example of both. This chapter concludes the creation path of a trading strategy. We initially introduced how to create a trading strategy idea, and then we explained how to implement a trading strategy. We followed that by explaining how to use a trading strategy in a trading system and then we finished our learning experience by showing how we can test a trading strategy.

In the next chapter, we will conclude this book by talking about your next steps in the algorithmic trading world.
