Please add a Fixed Dollar Amount as a filter option for Monte Carlo filters.

When Money Management is set to Fixed size or Fixed amount then % DD is pretty much a useless value.  If one starts with an initial balance of $10,000 and has a drawdown of $4,000 then the DD% is 40%.  If that drawdown occurs after the account balance has grown from $40,000 then the DD% is only 10%.  Since one never knows when the drawdown will occur, it could be the first trade, the last trade or anywhere in between, then the corresponding DD% could vary anywhere from 40% to 10%.  Therefore, when one is using a fixed trade size regardless of the account balance, the DD% should be computed based on the beginning account balance.

Another option would be to allow one to compare the Monte Carlo drawdown dollar value to a user supplied fixed dollar amount.  Currently one must use a % factor applied to the original drawdown dollar amount.

Example: Assume a maximum acceptable drawdown of 20% of the account balance. Starting with $10,000 then the maximum acceptable drawdown is $2,000 no matter when it occurs. Unfortunately, for the Monte Carlo Filters, there is no option to use a fixed dollar amount to compare to the 95% drawdown value. Since only a % multiplier of the original One strategy may have an original drawdown of $700 and a % multiplier of 280% would work in this case but the next strategy may have an original drawdown of $1,500 and a 280% multiplier would accept a 95% drawdown value of $4,200 which is more than double the acceptable risk threshold.

Thank you,
Dave

It should read like this:


When Money Management is set to Fixed size or Fixed amount then % DD is pretty much a useless value.  If one starts with an initial balance of $10,000 and will accept a maximum drawdown of 20% then the maximul dollar amount of the drawdown would be $2,000.  If that same 20% maximum drawdown is applied to an account that has grown from $10,000 to $60,000 then the maximum acceptable dollar drawdown then would become $12,000, $2,000 more than the starting balance. Since one never knows when the drawdown will occur, it could be the first trades, the last trades or anywhere in between, then the corresponding DD% could vary anywhere from 20% to 120%. 

Therefore, when one is using a fixed trade size regardless of the account balance, the DD% should be computed based on the beginning account balance.

always use ratios in MC tests - so RDD is enough by my opinion

Please disregard. I found out how to do it.

Thank you.
