# Historical performance metrics

KlickAnalytics runs thousands of calculations on price volume, fundamental, and time-series datasets. One of the important calculations is **Historical Performance**. We calculate the historical performance on various data e.g.

* **Open Price**
* **High Price**
* **Low Price**
* **Close Price**
* **Adjusted Close**
* **Volume**
* **Change ($)**
* **Change (%)**

and more. For each of the above, we calculate the historical performance based on duration i.e. 1 Day, 1 Week etc. e.g. for 1 Week Historical Performance, we take the current date and 1 Week prior date to calculate the percentage change. i.e.

```
For Historical Performance Calculation, we take:

1 Week = Current Date and Date 1 Week Ago
1 Month = Current Date and Date 1 Month Ago
1 Year = Current Date and Date 1 Year Ago
​​​​​​​5 Years = Current Date and Date 5 Years Ago​​​​​​​​​​ 
```

As a result of the above rule, we provide the following historical performance data;

* **1 Week**
* **10 Days**
* **20 Days**
* **21 Days**
* **1 Month**
* **50 Days**
* **3 Months**
* **100 Days**
* **6 Months**
* **200 Days**
* **9 Months**
* **1 Year**
* **2 Years**
* **3 Years**
* **5 Years**
* **10 Years**
* **20 Years**

Keep in mind that other websites could use a different calculation, so our historical performance value might not match those sources. We recommend checking with the sources you use to learn what calculation they use for historical performance calculations.
