Actually you can't have anything like a steady income from both gambling and trading ,at gambling maybe it would take too much lost before you can win and from trading it would take may days ,or a month before you can get a profit and the return of your investment.
You are right, in trading it takes time to earn its either weeks or months. i guess you can earn steady by enrolling in sig campaign but its not big.
but if OP have good money control investing with trading is good steady income if he can invest for a whole month for sure hes money will increase specially if OP will learn how to read graphs and movement.
