Stock Market Investor and Online Investor

I have been trading in the stock market for some time now. My own initial experience was a disaster , where i lost quitw a bit of money and decided never to try it again... But the fascination was always there and i decided to give it another try, this time with some caution and some good sound advice from an old relative of mine who never seemed to have lost any money, but always managed to make a tidy profit, never a great sum but nevertheless a steady income.. This is what he advised me... 1, Book your profits keeping a margin, never delay .. 2, Try to have some knowledge of the share movement of the stocks you have invested in 3,Try to buy some shares and trade with them only, like selling when they go up and buying back when the price comes down, and buying some more shares with any profit you make.This increases ones portfolio , so that you have more shares from different companies with which you can trade.. I find these tips very useful and now i trade only with the few stocks that i have and have had no bad experiences, there is always an up and down so with patience one can make a little profit every day..
