Position Sizing

Hi Pet, I have a full-time job in the software industry. Later stock market and especially CAN SLIM approach of investing stat attracting me. So recently I started trading in the stock market. Right now I am very confused about position size as to how much I should buy. I join you a month ago and religiously buying/selling whatever you post on Twitter. Plus I also do a few of my own Buy/Sell. From last month I could not make much of profit as I frequently stepped out from my buy. I started with a $20,000 buy position and am now reduced to $5,000-$6,000 buy position due to many losses I booked last month. I set up a stop loss to not more than 5-6% of my personal buy and the buy you recommend I do not put any SL and sell when you say so. Can you explain to me through a video how we should position size and what will be our approach when we start booking losses or profit in a given market time period? Do you always have a fixed position size to buy to start a trade or you adjust the position size based on how your performance from last month? Thanks in advance, -Anilesh Lakhtakia
