### Syntax

Starting from version 2013.01:

```
DataSeries ConsecDaysDown( DataSeries ds, double pct );
DataSeries ConsecDaysUp( DataSeries ds, double pct );
```

### Parameter Description

 bars A Bars object ds DataSeries that has declined/increased pct Percentage decline/increase

### Description

These indicators, developed by Dion Kurczek, display the number of consecutive days where prices declined (or rose) by a specified percentage or more.

### Example

This example illustrates how to create a simple trading system that buys after the closing price has declined 5% or more for 2 days in a row, and shorts when the closing price has increased 5% or more for 2 days in a row. It exits after 5 days in a position at open next bar.
