New article Category Theory in MQL5 (Part 10): Monoid Groups has been published:
This article continues the series on category theory implementation in MQL5. Here we look at monoid-groups as a means normalising monoid sets making them more comparable across a wider span of monoid sets and data types.
The application of this to traders will be considered in a manner similar to what we had in the prior article. Recall we are viewing monoids (the sets) as a pool of decision options a trader may choose from and in our last article we looked at extending the size of this pool with monoid-actions. We examined what impact this had on performance of a trading system if we extended scope of particular monoids based on a list of factors that weighed relative importance of the decision points (features) of the trade-system. The results were worse-off to average compared to what we had got in the article before that which considered restricted (default) monoids. For monoid-groups, rather than expand the scope of our monoid sets we will revert to restricted monoids that have had action and are transformed to groups. We will review the change in set composition following this monoid action but the actual implementation of a trading system will not be considered for this article. That is something the reader is invited to explore independently.
