Hi Tonyj,
Read both the threads you started. Have been dabbling in PnL since I was 18 years old in 1980. But never went past the first (Orange cover) book until last year. Did the usual "made 20k and lost 25k in a 4 week soybean run" but have usually been too busy to trade full time.
I am wondering if you think the PnL ideas are working well in forex.
