I would recommend reading Debunking The "Trading Options For Income" Myth
There are many crooks that will make you to believe that you can generate a consistent income trading options. Options trading is NOT an income producing strategy. If you want a consistent stream of income, buy dividend stocks, rental properties, bonds etc. When you are trading options (or any other instrument), there will be losing weeks, losing months and sometimes even losing years, no matter how good you are. If you see someone promising you a consistent stream of income from trading or investing, they are probably doing something similar to Bernie Madoff.
Also, trading is a business. As in any business, prices are involved, and our profitability of success will always depend on our ability to get good fills. Every business revolves around this cost equation... If getting good prices was so easy, there wouldn't be any markets/any business. So there is no such thing "trades that are not as dependent on entry and exit prices"
Sorry to be blunt, but I always tell people the truth, and not what they want to hear. If you want to succeed in trading, you must put time and effort. Otherwise just buy index funds.
