I have been trading for around 4 years in Options Trading and I have seen many ups and down as well.
I would like to clear one thing here , there is no magic wand in this whole world which you wave and you will get 100% accuracy in trading. If you are looking for such thing , then I would say sorry and its impossible.
Trading is all about maximizing the profits and minimizing the losses but in general traders do vice versa and end up in big losses.
