As was explained many times,
all R/S and PP levels are KNOWN a day before the current session.... The numbers are calculated by using previous session DH, DL, DC (day high/low/close, some traders may use slightly different definitions, but results are usually very close.
Conditional on existing info, usual trading is mainly determined by the first two R/S levels ... That's why it is a common practice to provide R1,R2 & S1, S2 only. However, ALL R/S levels (3,4...) are fixed by previous trading period and cannot be changed.
