You should follow your own advice more. Dips are designed to take out all longs. This is why neither following the trend nor buying the dip works. These things only look good on historical data, lulling the curve fitters into thinking they have something when they don't.
Because I want to be ready & confident when I do open my futures account. If these SIM trades don't work well how can I trade real money confidently? I'm putting in 12 hr days developing & testing strategies and whatnot. It's exhausting, and heartbreaking when they don't work out, time and time again SIM or no Sim.
