$Tiger Brokers(TIGR)$ just wait and wait. Simply wait till the price is cheap to buy and wait till the price is high to sell. My own experience. I bought Boston scientific at USD42. It dropped to USD 5. Now it's over USD100. Profit is coming from your patient, not your intelligence or even experience. There is no time limit for you to wait. That's our advantage, different from the big investment company. we can take that advantage.
