multitype dynamic multi registry with categories 3d matrix

using matrixes, and overloads.. a complete parallel multiregistry, multitype,multikey datastore.
it can use get, set, delete, with as many registries and individual matrixes as the system can handle.

system >
registry
category names
key names for each item
value (( to x/y in value matrix)
value matrix
item in x/y coords

so putting item 'float XXX' with a value of XXX (ohlc..) for category 'ohlc values' into value matrix floats, floats1 for hist... etc.. historical value for the past X num of bars for all 4 values in historical matrixes..

here's an example..

almost done testing..
very powerful tool

anyone with extensive skills who can take a look at it, i'm open for help prepping and finding any optimizations available

as is, it is very very fast..
i believe i can improve though from here.
