I developed a simple script for myself, which runs every day and compares the collections.
It shows three numbers in columns for each day. The left-most column is today, and the rest are the previous days.
Each column shows three numbers: count of strategies, count added, and count removed:

It helps me to see the general effect of the Acceptance Criteria.

I have a workflow of 6 stages, stage 1 is generating, stage 2 is testing out-of-sample, stage 3 is testing on another market, etc.

I need to see how many strategies were dropped after each stage and the criteria they were dropped on, for example, less than 100 trades, or PF is less than 1, etc.
