Trading spy weekly options
Before I got mixed up with him I knew zero about the currency markets, about fundamental analysis, technical analysis, economic and technical indicators, time frames, Fibonacci sequences, NOTHING. But by the time he had finished taking me for all I had I had passively picked up quite a lot of quite useful knowledge. A lot of it was complete BS as well, this I started discovering as I began looking into the Forex markets on my own.
It was like having a silent evil teacher right there in the room with me and as I learnt more I began cutting into all the bullshit he had sold me. I remember the point at which I finally realised that I had learned more about trading than he even knew, it was a very weird moment.
