How to determine lot size in Trading View

Hi, I reading through different posts that are discussing lot size. I understand a 100,000 units is a “lot”, however, I am a bit confused on how to calculate a “lot” it in Trading View.

If I am trying to purchase 1.5 lots of CHFJPY, how do I calculate that based upon risk and SL?

1.5 lots is $10.50 per pip

How do I go about calculating say 1.5 lots of USD/CAD?

Trading lot decision will be taken by the forex traders as per their need. For example: if you are a risk adverse traders you may require to work with smaller trading lots to keep your money safe in minimum investment. while if you desire to make bigger profit then it is essential to choose bigger lots in return fro the bigger profit.
