Modifying 2 pre-made indicators_2008010001

I have a request of modifying 1 pre-made indicator.
Firstly, take a look at below image, please.
There is “A”, “B” and “C” on above image.
I need extra 2 buffers for calculating “A”, “B” and “C” for current pair (EURUSD).
Now, EUR == -64 and USD == 138 in section “A”
Value of EUR is not the strongest or the weakest.
Sometimes, “EUR” can be the strongest, and also “USD” can be the strongest.
Here is a table value for calculating it.
There are 7 currency and 7 slots in “A”, “B” and “C”.
For example, there are 7 currency and 7 slots in section “A” as followings below.

For more details, take a look at my document attached, please.
Thanks,
David
