This package includes my best short systems appropriate for current bearish market conditions.
It includes 7 systems: The Head & Shoulder, Double Top, Overbought in a downtrend, High Volatility (Short),Rectangles (Short)  
and the Sperandeo 123 and 2B systems.
You can purchase these systems for the Amibroker and Metastock platform by clicking on the appropriate tabs at the left.
You can see below the performance of all systems during the last year (23/9/2021-23/9/2022).

This is how the systems performed during the last year until the 23rd of September 2022.
To produce the test results I used Amibroker Pro with the following test parameters:
Max. Open positions: 12
Commissions: $0.01 per share
Volume filter: Limit position to 5% of trading volume
Entry & Exit next day at the open.
