How position sizing can affect your trading performance-
Assuming that you are trading a Trend-following system with Big RR and low win-rate.
For example, assume that you risk one percent per trade on a 100,000 account
and you have 20 straight losses.
That one percent is of your remaining equity and at the end of 20 losses, you would be down to 81,790.60.
Now if you got a 30R winner and you are risking one percent of your balance of 81,790.60, your new equity would be 106,327.9,
You’ve had 20 losses and one winner though you are still up 10Rplus your equity is up by 6.3R percent.
Now, let’s say you risk five percent per trade on your balance. At the end of 20 straight losses, you would be down to 35,772.89 or down 64 percent.
If you risk five percent on this amount and get a 30R winner, you would be up to 89,621.48. You are up 10R, but because of your position sizing, your equity is still down over 10 percent.
If you are a Positional trader then Keep your position sizing as such that even if the stocks open 10% down, your account should not be down more than 5-6 %.
Lets understand how to deal with risk when you are a positional trader,
There are two types of Positional traders,
1. Those who hold stocks with 1-2 % SL for 4-5 days, though they call themselves swing traders
2. Those who hold stocks with more than 5% SL for 15 days to 1 month
Both type of traders have one thing is common, which is overnight risk
Now Most people who lose there pants overnight belong to the first category, who hold with 1-2 % SL.
lets know how and why?
You may have set your SL as say 2%, but can you control how much the market moves overnight, no, right.
