Formulas for Constants & Variables

[loutaang]

Hi. I have a questions.

1. How do we use Formula?
2. How do we use constants and variables?
3. Let's say I have S/L at the lowest price (candle period) but I need to adjust the S/L by 10 pips. All I can think of is by using the formula but I don't know how. Someone please help?
4. Is there any link or video that can help me with these?
