Timeframe and ichimoku – how to get values from other timeframes?

Hello,

I encounter a problem with timeframe used for ichimoku.

I have create a function “ICHIMOKU-FUNCTION” and I call it with the instruction CALL. For information; this function return the trend (1, -1 or 0) depending on the position of the price versus the kumo.

If I execute the here below code from time frame 4 hours (calling the function under 4 h timeframe), I get no issue (result is the right one).

If I execute the here below code from time frame 1 hours (calling the function under 4 h timeframe), I get no issue (at least something close to expected result).

If I execute it from the time frame 15 min or 5 min or 1 min (calling the function under 4 h timeframe), I do NOT get the right result at all.

Any idea where it could come from ? (I am not so used with prorealcode so perhaps I miss something basic)

Thank you

TIMEFRAME(240 minutes)

Trend240=Call "ICHIMOKU-FUNCTION"[ToleranceTenkKijun]

TIMEFRAME(default)

// 4 HOURS
IF Trend240=1 then
DRAWPOINT(barindex, -0.4, 2) coloured (0,128,0,128)
ELSIF Trend240=-1 then
DRAWPOINT(barindex, -0.4, 2) coloured (128,0,0,128)
ELSIF Trend240=0 then
DRAWPOINT(barindex, -0.4, 2) coloured (255,201,14,128)
ENDIF

return

Thank you
