"But when you call a broker, place an order, and then watch the computer screen to tell you if you made the right decision,"
Yes that is exactly true and seasonals wont help you today or this week. And as this forum has seen time and time again your timing has been 'WEEKS' early with prices continuing to rally such as CORN etc. And if taking your over hyped 'EXACT' tops as predicted everyone would have gone broke a long time ago. Your past posts going back to spring clearly show that.
People in glass houses shouldn't throw stones!!!!! Making EXACT tops predictions with a record of them is never a wise choice. And you just can't keep explaining them away as time goes on like you do. And it is costly to anyone trying to actually TRADE off of them! This chart tells the true story!
