Completing the Babypips course will be a good starting ground.

First point: those are the markets that are hopeless for forex scalping.
Second point: scalping and retail forex trading are mutually exclusive anyway, for several reasons, but the main one is that the person you think of as your “broker” (and the Babypips course unfortunately refers to that way) is actually your counterparty and would be the party being scalped. Nobody minds you scalping the market, but with a retail forex broker you’re not in “the market”: you’re only in “their market”. Which is why it doesn’t work. (But at your times of day, forget it anyway, even with a genuine broker, if you have that kind of capital.)
