I use my iPhone to trade. Can trade any where as long as there is internet connection. Mommo app very good, provide all the info I need to decide on a buy or sell call. I buy when everyone is selling and sell when everyone is buying. The rest of the time just watching.

Buy the stock that is on sale after it has hit it’s recent low and selling volume has decrease. Sell when the stock has moved to new high and volume of buy has decrease. Don’t force to trade, wait patiently for the opportunity to trade.
This is my best cure for buying high and selling low.

I installed solar power system, and also consciously try to minimize electrical wastage. Drive a hybrid car. Not wasting is my moto for staying green.
