Thanks. In the spirit of parsing, the forbidden period during which replacement triggers wash disallowance/adjustment is 61 days: the sale date, the preceding 30 days, and the subsequent 30 days.
I hear you about nexus. That makes me wonder if standing orders to different brokers to implement the same rule-based trading regime would be enough to obtain it, if each was unaware of the other and the trading results of both were subject to the vagaries of order execution. Isn't that the theory in Hunt, that they sometimes were selling to each other but didn't know it?
