Steady Tiger
Past performance is no indicator, though you can sometimes (and in exceptional cases) pick out a trend.
If you are certain that the price will DROP, as you have intimated in your posts - ie you will buy now (otherwise why bother to post at all?!) and sell when the price drops then what you are talking about is the derivatives market, not shares.
You therefore require a derivatives trader happy to operate on an execution basis, not a stockbroker!
Be wary though - the derivatives market is an unforgiving place where both profits and losses escalate very rapidly........
