This method says
: independent of the account state, always enter the position
with the same Sum. Although this method is fairy safe, it
does not allow the account to grow in geometrical progression.
If this strategy is selected, an equal dollar position size
is established for each trade. The number of shares is determined
by dividing the price of security into the desired position
size.
Formula:
Number_of_shares = Fixed_Sum / Security_Price
Example:
Fixed Sum - 2000 $
Security Price - 20$
In this case you can buy 2000 / 20 = 100 shares
