DD calculator indicator

I want an indicator which can give me relative DD of my every chart running in my account. 
For example Let's imagine I am running the following 10 charts in one account

My DD is 18% for today and my Maximum DD on the account has been 27%

I want the indicator to record the percentage of each chart for the Daily DD and each chart's Maximum DD in all time history.

for the above example

XAUUSD >>>>> 5%

EURNZD >>>>> 1%

EURCAD >>>>> 0%

EURUSD >>>>> 2%

USDCAD >>>>> 3%

EURGBP >>>>> 0%

GBPUSD >>>>> 1%

GBPNZD >>>>> 1%

GBPAUD >>>>> 3%

NZDUSD >>>>> 2%

TOTAL Daily DD >>>>>> 18%

I also want the maximum DD of each chart in the account.
What is the maximum DD of each chart in all time history. 

The indicator can simply be designed by dividing each chart's Exposure to account's balance and multiply it by 100 to get the percentage. and record it in a table and also record each chart's all time high DD in another section.
