Kotlin project

[kinggatsheni2]

I have this app I'm bulding that the interfere I have to take user inputs from first edittext and second one and display answers on the 3 text views one lebeled no of pips to hold, expected loss and third one for displaying lot size I'm having trouble writing the code in kotlin to do so I'm a beginner
For for lotsize = (equity*((risk/100)*500)/100 000
Formula for no of pips to hold = equity*(%risk/100)/(lotsize*10).
Formula for expected loss = pips*(lotsize*10)

What part of this are you having problems with? Please show the code you've written so far.

I'm having problem on how to implement those formula's

Slightly confused here. You've shown a screenshot, so there's some code behind this. Let's have a look at that code.
Your question can't really be answered until the context is understood i.e. how do we get the values of 'risk' and 'equity'. Judging by your screenshot, there are a couple of EditText components holding those values. So until we see the code behind the screenshot, your question can't be answered.

I'll post the codes now
