so I guess what I am saying is that NOTHING is 100%, be it indicator based or not.
I doubt any price action trader would disagree with you. All DbPhoenix suggested was that the very divergences that indicators signal with a bit of lag can usually be picked up a bit earlier by someone trading price. This can be discovered rather easily if one decides to view price in terms of discreet bars of one's selected bar interval. For example, stochastics measures the close of the most recent bar relative to the range of the most recent n-bars. If the bar of the prior swing low closed on its low, and price has just re-tested that swing low by making a lower low but the current tick is above that low and higher in its range, you might have what we scribblers lovingly call a "dog that didn't bark" long opportunity. Whereas someone trading the indicator alone may also be looking for a long signal - but that signal might first require the current bar to close, thus ""confirming the divergence" and then the netry might require wating for the high of that bar to be broken as "further confirmation. By this point, the price action trader might be close to scaling out with the first batch of profits and moving his or her stop to breakeven. The indicator trader, using bars to frame much of their trading, is thus getting in later, likely using the low of the signal bar as a stop loss, and therefore assuming greater risk.
None of which is 100% for either trader. And one can debate the price action trader's greater information risk vs the indicator trader, but one would need to frame that debate in the context of the greater price risk assumed by the indicator trader.
