What is the best FTMO strategy?

That's the million dollar question! There's no "correct" way. We've noticed support and resistance is a popular method, but this is manual trading which doesn't suit everyone. We prefer automated strategies. Manual trading is more efficient, but labour intensive. The inefficiencies of automated trading need to be overcome with money management, and a system that compensates for imperfect entries. 'Averaging' is a method of allowing for imperfect entries. This involves running multiple small trades, adding new positions when the price moves backwards. Positions are small, and the trades are definately closed for a loss at a reasonable threshold. Never infinately add positions or use martingale etc. It's guaranteed to blow your account eventually.
