90201If by grail you're feeling a system that churns out money if you follow it blindly, then yes-- temporarily. Traders here who've been around understand that markets grow. If traders do not adapt to these modifications they're left wanting to make sense of patterns which no longer have any worth. This is not to say that just discretionary traders are powerful. Mechanical (system) traders can/do triumph, but they adapt their methods. Quant traders possess progr that constantly spit out cash because of their small (yet profitable) borders, however they frequently tweak those progr with time.
Good fortune,
