In an equity account, a regulated trading account, the broker needs to accept the LTA and that person as someone they will allow that function. We do quick background checks. What if that person is barred from the business or has financial felonies etc. On the Futures side, there is all that plus the CME wants to know who the trader is. Each platform can only be issued to one trader. So yes, the LTA must be filed and excepted.
