guppy count back line

This is the MT4 code for the Guppy count back line if anyone is game enough to try and convert it to PRT.

CBLhi:

HighDays := Input(“Enter # days to cover last HIGH for CBL calc’n:”, 3, 55, 13);

If(HIGH < HHV(HIGH, HighDays), {then …} PREV, {previous CBLhi, else…} If(Ref(L,-2) < Ref(L,-1) AND Ref(L,-2) < L AND Ref(L,-1) < L, {then …} Ref(L,-2), {2nd day back low, else…} If((Ref(L,-3)< Ref(L,-2) AND Ref(L,-3) < Ref(L,-1) AND Ref(L,-3) < L) AND (Ref(L,-2)< L OR Ref(L,-1) < L), {then … } Ref(L,-3), {3rd day back low, else…} If((Ref(L,-4)< Ref(L,-3) AND Ref(L,-4) < Ref(L,-2) AND Ref(L,-4) < Ref(L,-1) AND Ref(L,-4) < L) AND (Ref(L,-3)< L OR Ref(L,-2) < L OR Ref(L,-1) < L), {then… } Ref(L,-4), {4th day back low, else…} If((Ref(L,-5)< Ref(L,-4) AND Ref(L,-5) < Ref(L,-3) AND Ref(L,-5) < Ref(L,-2) AND Ref(L,-5) < Ref(L,-1) AND Ref(L,-5) < L) AND (Ref(L,-4)< L OR Ref(L,-3) < L OR Ref(L,-2) < L OR Ref(L,-1) < L), {then …} Ref(L,-5), {5th day back low, else…} PREV )))))

and for the CBL from a LOW

CBLlo:

LowDays := Input(“Enter # days to cover last LOW for CBL calc’n:”, 3, 55, 13);

If(LOW > LLV(LOW, LowDays), {then …} PREV, {previous CBLlo, else…} If(Ref(H,-2) > Ref(H,-1) AND Ref(H,-2) > H AND Ref(H,-1) > H, {then …} Ref(H,-2), {2nd day back high,else…} If((Ref(H,-3)> Ref(H,-2) AND Ref(H,-3) > Ref(H,-1) AND Ref(H,-3) > H) AND (Ref(H,-2)> H OR Ref(H,-1) > H), {then … } Ref(H,-3), {3rd day back high,else…} If((Ref(H,-4)> Ref(H,-3) AND Ref(H,-4) > Ref(H,-2) AND Ref(H,-4) > Ref(H,-1) AND Ref(H,-4) > H) AND (Ref(H,-3)> H OR Ref(H,-2) > H OR Ref(H,-1) > H), {then… } Ref(H,-4), {4th day back high,else…} If((Ref(H,-5)> Ref(H,-4) AND Ref(H,-5) > Ref(H,-3) AND Ref(H,-5) > Ref(H,-2) AND Ref(H,-5) > Ref(H,-1) AND Ref(H,-5) > H) AND (Ref(H,-4)> H OR Ref(H,-3) > H OR Ref(H,-2) > H OR Ref(H,-1) > H), {then …} Ref(H,-5), {5th day back high,else…} PREV )))))
