Just bolting down my money management system and have a question about how the more seasoned traders handle it.
I’m basing my money management on % of available equity
I calculate the potential loss and ‘equity margin’ of all open trades by multiplying the pip value by the stop loss then subtract this from the available equity. This ensures I can handle the swings
So if I have 3 open trades with 100 pip stops and $0.10 pip values that’s 300 x $0.10 I deduct from from the available equity figure I have to trade with (minus margins for new trades as well).
Now my question is - should I calculate the size of my positions (in accordance with my money management rules) on a trade by trade basis?
Or should I have a weekly position size for all trades that I review at the end of each week and recalculate according to the account balance and available equity?
Here are a couple of examples - let’s say I’ve seen a very nice valid entry to a trade:
[B]Option 1.[/B] Money Management - trade by trade on % of available equity
I have 5 trades open and my regular position size is 0.02 however the % of my available equity and money management dictate that for this trade I can only take a 0.01 lot size
[B]Option 2.[/B] Money Management - Weekly lot size
I have 5 trades open and my regular position size is 0.02. My available equity can easily handle another 0.02 position with my regular stop loss.
I can see the benefit of both options but I prefer option 2 because trade number 5 might be a particluarly good one and if my account can comfortably accomodate another position with my weekly position size I should take it.
Please bear in mind that my system uses intraday/position trading and trades are held open for days and sometimes even weeks.
