Stock Screener – Example 4: Multiple Scan Blocks (like a screener)

This is an example of an optimized scan that demonstrates using “Multiple Scan Blocks” to mimic a screener; it can replace the need for maintaining several scans (as was required in the older versions of ChartAlert)

1–2 minutes

This functionality was introduced in October 2023 (Version 23.10.1)

Below is an illustration of an optimized scan that can be created using the Advanced Scanner in ChartAlert.

This one enhanced scan now replaces the need for maintaining two separate scans as was required in the previous versions of ChartAlert.

These Multiple Scan Blocks actually function like a screener, by incorporating two sections of code (each marked with its own BEGIN/END statements) designed to identify and analyze two separate conditions.

[BEGIN close>ema(20)]

List symbols where c > ema(20)

Add Column Close
Add Column ema(20) chart(lw=2)

Apply to NIFTY500

[END]

[BEGIN close<ema(20)]

List symbols where c < ema(20)

Add Column Close
Add Column ema(20) chart(lw=2)

Apply to NIFTY500

[END]

Below is a breakdown of the scan presented in a step-by-step manner.
