This wont work ftr.  The pool marks whether you auto-trade or not at the time the each round ends.  This is because it has to know how much of that rounds earnings get paid out in doge vs. get sent off for auto-trading.  Turning auto-trade back on later will only affect future rounds earnings.  In addition, auto-trade will never trade your already confirmed balances of coins, it only ever deals with coins mined in recently active rounds.
