2 way communication system

Hello Devs !

I got an interesting proposal for you guys.

I am trying to optimise my trading skills and create a bias thingy for me and a friend of mine, so that we have a mutual bias before opening trades. So to this extend, I'd require the following things:

1. An input indicator that has a small display on the screen for each strategy I use, that i can click, and get updated online.
2. An output indicator, that writes onscreen the bias for that symbol.

So for example, if i have strategy 1 & 2, and my friend has strategy 3 & 4, we will both have an indicator toolbox to do the following:

I will have on screen strategy 1 & 2 with clickable buttons saying i'm SHORT / LONG / NEUTRAL on that specific pair & timeframe
he will have an on screen thingy for strategy 1 & 2 with clickable buttons saying i'm SHORT / LONG / NEUTRAL on that specific pair & timeframe

and we both will have an output indicator that will display the following.

========= ME ========       ====== Friend 1 =======
Strategy 1      Strategy 2      Strategy 3       Strategy 4
h1  h4  d1      h1  h4  d1       h1  h4  d1       h1  h4  d1

S    N    0        L    L    L         L    N   S         0    0     0

S = short, 
L = long
N = neutral
if i don't have a bias on that / i don't have that specific pair in my marketwatch, the indicator should display 0 or nothing..

I'm not picky on the way it looks, i just want the utility of it so that we can always have our biases synced.

The indicators should be scalable, meaning that more people could join and each and everyone can have as many strats as possible. It should also display when the bias was lastly updated.

PS. I'd also want some way that i can limit access to viewing / writing ... so for example if a 3rd friend joins, i'd like to be able to kick him out of the project if needed, or just to limit his view & wringing possibilities

Thank you all for your time!
