Notes

Repricing

When useRepricing = true the connector will use special transaction identifier: place_bulk_orders_to_subaccount_with_repricing.

Max Collapse Size

This is the max quantity that will be re-priced at the top of the book.
Max Collapse Size can be optionally passed in MassQuote::Issuer property.

for example if max_collapse_size = 50,000

• Case 1: total size that would cross before repricing = 10,000 (< 50,000) so full size 10,000 will be repriced at top of the book price (1 tick away from best).
• Case 2: total size that would cross before repricing = 100,000 (> 50,000) so size 50,000 (max) will be repriced at top of the book price (1 tick away from best).
