That I would also say just risk the identical sum of money on every trade.
For instance $10 on every transaction, so the most you'll lose is $200 approx.
However it is unlikely you will lose them all, even a coin toss must create a few winners, never the less it is possible. If $200 is too much reduce your risk. (or demo trade)
having the ability to keep playing your advantage even after a series of losers is a significant part of what separates the winners from the losers
Depending on your risk reward you might only need to win 30 percent to be at BE.
As soon as you do the 20 trades review all the results. Keep thorough notes, screen shots and records.
Watch those videos I just posted, Mark talks about that in detail.
