Traders lose because they are making market timing decisions on an essentially random moving target. Random walk is not a perfect description of price movement, we all know that, but it is still the best model. Traders use indicators in an effort to get better than 50/50 odds, but random walk shows us that's not generally possible (notice I didn't say impossible.)
I'm not a big fan of options for a number of reasons, but how can one trade probabilistically on just the underlying, and not use options.
