Writing my Pips in Trade Journal

Dear All,

I have start with a trade journal which I try to fill in as accurate as possible… because i don’t always use the same capital to buy or sell, i also want to write down in pips. But I don´t understand that pip things I guess…
I´m not only trading Forex but also stocks.

For example:

When I Buy at 1.0001 and sell at 1.0002 I have 1 pip right?? (4 digits after dot)
But when I buy a stock at 72,03 and sell it at 89,80 how many pips did I win?? Does I need to change it to 4 digits then?? (72,0300) That is a lot and seems to me incorrect!

Pls explain.

Rgds,

Menno
