NNFX Money Management / Risk Strategy

[SirBoyce]

Hi All,
I thought I would try out NNFX's strategy/advice for money management in an EA. Essentially it is this:

1. Express current ATR value in pips (ATR X 10,000 = ATR_PIPS)
2. ATR_PIPS X 1.5 = Stop Loss pips (SL)
3. 2% of current balance = RISK
4. RISK / SL = Current PIP VALUE
5. Calculate Lot Size to reflect current PIP VALUE so risking only 2% of balance on the trade

I created variables and formulae in the following to cover 1-4 of the above: https://fxdreema.com/shared/wTS8dsTI

My questions are as follows:

1. Is this (creating the variables and formulae) the right way to go about achieving this?
2. If so, where and how are these formulae placed/linked in the EA?
3. How do I convert PIP VALUE to Lot Size and add this to the EA (e.g. another variable and formula?)
4. How should the resultant variables be loaded into the Buy / Sell blocks?

Many thanks in advance!
