Sterling. Understood. Read the other post as well. Just wanted to make sure of the concept of putting it 'all in' at each level is what you were saying. I understand the concept of exponential growth. It't like that question - I'll give you $3 million now or a penny doubled for one month....and you hve to answer right now. No thinking bout it. Like you said...there are MANY variables to consider when playing the market when deciding your play - entry, exits, losses. It goes on and on. thanks for getting back to me.
