Running a portfolio backtest and notice the following.
If a very large amount i.e. $25,000,000 is used as the starting balance the results produce an account size required much smaller, i.e. $7,500. When using an amount on the next test, everything else begin the same, something closer to the reported required account size such as $25,000 the results are significantly different, producing a much lower profit. Yet the account size is ~ three times the required account size for the portfolio test. Why?
