tradingview pinescript cannot use mutable variable in security function as an argument

Question

Before writing this i tried certain idea given here still not working so asking again.

This is the V4 code V2 =True SarUp interger vlue emaslow integer value //code from here

get_pltval(V2,sarUp,emaSlow) =>
    pltval = 0.0
    plval := V2 ? sarUp <= ohlc4 and sarUp[2] > high and sarUp[3] > high and sarUp[4] > high ? 1 : 0 : ohlc4 > emaSlow ? 1 : 0

var _src = 0.0 
_src := get_pltval(V2,sarUp,emaSlow)

test = security(syminfo.tickerid, tf, _src, barmerge.gaps_off, barmerge.lookahead_off)

Error Cannot use mutable variable as an argument in security function

Any solution this problem .Please share

barmerge and lookahead are "off" by default, so no need to explicitly define them. You can call a function from security():

//@version=4
study("")
get_pltval(V2,sarUp,emaSlow) =>
    pltval = 0.0
    plval := V2 ? sarUp <= ohlc4 and sarUp[2] > high and sarUp[3] > high and sarUp[4] > high ? 1 : 0 : ohlc4 > emaSlow ? 1 : 0

test = security(syminfo.tickerid, tf, get_pltval(V2,sarUp,emaSlow))
