I'm looking for an edge… It must have few indicators or variants It must work on all counters/stocks bonds , indices , currencies , commodities etc. It must not need any backtesting . . . All past potential trades should be clearly visible. It must eliminate lag in moving averages It should be able to withstand stress-tests Technical analysis should be mathematically verified. It must be able to scalp , day/swing trade and pick long term tops and bottoms It must not die on me.
