Market Activity Indicator / Buy Pressure Formula needed

[endeffects]

I have a list of the buy volume size and the involved order count.
Now i'd like to calculate an index for the current buy pressure
for each row to reflect the increase or decrease of the activity.

The list itself will be updated with additional rows on each tick.

Volume;Count
51;141
49;146
50;154
52;158

1. You will have to define what you mean by index. Only with concrete definitions can it be coded. Perhaps just a moving average will suffice.

2. You have only four choices:
   • Search for it,
   • learn to code it. If you don't learn MQL4/5, there is no common language for us to communicate. If we tell you what you need, you can't code it. If we give you the code, you don't know how to integrate it into yours.
   • Beg at Coding help - MQL4 and MetaTrader 4 - MQL4 programming forum or Need help with coding - General - MQL5 programming forum or Free MQL4 To MQL5 Converter - General - MQL5 programming forum or Requests & Ideas (MQL5 only!),
   • or pay (Freelance) someone to code it.
   We're not going to code it for you (although it could happen if you are lucky or the problem is interesting.) We are willing to help you when you post your attempt (using SRC) and the nature of your problem.

I would build an array of the volume differences:
V1: -2
V2: 1
V3: 2
...

then apply TEMA on that array.
