I have had a number of emails from people wanting to know what trade sizes they should be using according to the size of their accounts.
I’ve decided to write this post (based on my own experience) as to how I think you should choose your trade sizes according to your account.
Acceptable risk
I always advise people to risk between 3% and 5% of their account on a single trade.
That means: If you have an account of $10 000, you risk between $300 and $500 on a single trade, no more.
The reason for this is simple. Everyone makes mistakes and nobody’s analysis is right all the time. By limiting your risk to 5%, you pretty much ensure that you will never go broke or blow your account because you can have over 10 consecutive wrong trades and still have over 50% of your account left to trade with.
I have been watching these markets for 4 years and still make mistakes and bad calls. People who have been doing this for 20, 30 and 40 years still make bad calls at times. That is why it is very important to limit your risk.
Trade Sizes vs Trading Accounts
I mentioned the acceptable risk first because it is relevant to your trade sizes.
If you want to stay within you acceptable risk and trade like me (withstanding swings of a few hundred pips) then you need to make some calculations of your trade sizes.
With a $10 000 account I think it is safe to trade at a size of $1 per pip. This means that you can withstand a swing of up to 500 pips and still stay within your risk of 5% of your account. $1 per pip is a lot size of 10 000 (plus/minus).
With a $100 000 account I think it is safe to trade at $10 per pip. This means a lot size of 100 000 and with one lot you can withstand a 500 pip swing against you at be within your 5% risk limit.
How I Like to Trade
If you have been following my analysis for a while you may have noticed that I like to trade in ranges.
Since I cannot determine exact points of entry (although I try), there is always an obvious 1st 2nd and 3rd level where I expect it to turn.
I like to enter trades in sections of up to a few lots, starting with one at the first obvious level and adding up to the 3rd level. After that I place my stop at a level where the risk is acceptable if my trade is incorrect and then wait and see if the trade goes as I expect it to do.
Another thing I’d like to mention although it’s fairly obvious is that as your account grows you can and should adjust your trade sizes accordingly to stay within that 5% risk limit.
I hope this helped!
Cheers
