That's like saying, "If I didn't lose, I would have won."
The ever changing nature of the market is what makes day trading extremely challenging compared to a swing trader or long term trader who can wait for the exact right moment and not have to be in the market every day.
I believe TST still offers customized combines where you can stretch it over a longer time period though.
Regardless, here on ET there's traders who extremely rarely have losing days, year in and year out. It's quite impressive.
I guess that's what we all should aspire towards instead of making excuses. I know I am.
