I'm here, 4+years indices trading and 10 years prior stocks trading.
It sounds like from both your posts you have a problem with accepting its your fault, even if you doubt this then question why you state that 95% of spreadbettors lose, is it any different with DA, you also ask for specificly spreadbettors, again, is it any different going DA.
As for advice:
Go over your paper work and check the trades that you made. It's very possible you gave up on a good strat when it went through a bad period only to pick up another one and trade that equally bad with bad timing.
Remember, we all see the same prices and at the same time, this is true for all traders all around the world, so ask yourself, why does one person win consistantly and another lose.
This can also be attributed to the popular game of poker, more people lose than win, this happens year in year out and every single day, yet, the same people consistantly get near or at the top of the tourny boards. Surely the game is not rigged, they all get random cards yet it is not the cards you get....its how you play them.
Good luck
