What exactly do you mean by cutting my position size? First let me state that 0.01% of my account is $1. Ok now let’s work with some round numbers. Because, like you, my maths is poor. So let’s say I want to go long on ABC at $10 for 100 shares. So every move in the stock by one penny equals $1 to me. So should I limit my loss to $1 and get out if it falls to $9.99? Usually the stocks I'm in move back and forth a couple of cents every second. Or should I just be in for 1/10th of a share (0.01% of my account)?
As far as reducing the number of stocks on my watch list I think I actually have the opposite problem. But I'm just starting so I'm not really sure. Right now I only have about 5 in there and tomorrow I might only trade on 1, but it is only the end of my second day. Do you think that is too many or too little?
Hi dtcracker,
Position size is the number of shares traded. Start VERY small and add more when your results warrant it.
Attached is a chart that I use which I've modified for you, based on the info' that you've provided. I always factor volatility into my position sizing and for that I use ATR. The 'Max Stop' is set at 1.5 times the ATR (set to the default of 14 periods). THIS MAY BE TOO WIDE OR TOO NARROW FOR YOU AND YOUR STYLE OF TRADING. Sorry to 'shout', but this is very important. It may be that you can trade with a much smaller ATR setting or, conversely, you may require a much wider setting.
Anyway, the idea is that you look at the ATR reading on your chart and then at a glance you can see the quantity of shares you can trade, the maximum share value (without margin), the maximum stop and target. The point about Value is that suppose you're looking at AAPL, for example, trading around $170.00 per share. At a glance you can see that you can trade a max' of 50 shares.
The target is based on 1.5 times the max' stop which, again, may be inappropriate to you and your style of trading. This offers a R:R of 1.5:1. Some people wouldn't take a trade that offered a R:R of less that 3:1, but these figures are easily changed. The max stop is set at $25, i.e. 0.25% of a $10,000 account. I suggest you start with this and build up as your confidence and experience grows. More to the point, as your results warrant it.
There are all kinds of electronic versions of this chart on the net which go into all sorts of fancy calculations if you're into that sort of thing. I like this because it's instant and easy.
Let me know if anything isn't clear.
HTH
Tim.
