this post is spot on.
there is really only 1 reason - no edge.... and that comes from no training, no information etc.
As a trader, what keeps me trading is I believe I have an edge. What is that edge? I win 40% of my trades and lose 60% of my trades. My average win size to average loss size is 2 to 1. So, what is the edge? P= (.40)(2)-(.60)(1)= .80-.60 = .20 or I win $0.20 for each $1.00 invested. Now, I am not the best trader here or anywhere for that matter. How much will I earn? Who knows? It does not really matter as long as I make more monies than I lose. I have also, spent monies I earned from the market. To each his own. Sometimes, I get windfall profits like on TWTR put options where I made $2300 in 3 days time. Lost $700 on my calls on RUN. Earned $600 on INTC calls in one week. Where else can I earn that much monies in a short period of time? Why would I stop trading and settle for 15%-20% in one year? My risk is limited to the cost of the options premium. Upside on an uptrend for call options unlimited in theory and limited to zero on the downside for put options.
