GLOBAL_INDEXES_OBSCURITY

When we get the global indexes, we pass in a range of blocks, to obscure which transactions we are interested in - the ones that belong to us. To do this, we get the global indexes for all transactions in a range. For example, if we want the global indexes for a transaction in block 17, we get all the indexes from block 10 to block 20.

This value determines how many blocks to take from.
