Let me give you one piece of advise: Put that 20K in the bank and forget about it.
Yes it may seem harsh but you are in no position to trade yet. Trading is not easy. If it was easy all traders would be rich. 95% of traders blow up. I suggest learning and observing the markets for a period of months, getting youself a small
demo account (some places let you open for 500 bucks), learning about trading psychology, trading in a successful method. And then after 2-3 months of consistency is a variety of market conditions (chops, ranges, trends) you MAY be profitable if you trade that 20K.
Of course dont take my advice if you are willing to give up that 20K. Just some advice.
