pine script - Pinescript : Round of nearest 0.05 in decimal places

Question

I wish to round off any values to the nearest tick in decimal points. For example if the calculated TP or SL is 101.68 it should be rounded off to 101.70 my ticker's decimals moves in 0.05 increments.

In Metatrader4 I acheived this as

price=NormalizeDouble(price-NormalizeDouble(MathMod(price,0.05),2),2);

How to achieve this in Pinescript?

Answer 1

//@version=4
study("Round to tick", overlay=true)

f_round_up_to_tick(x, mintick)=>
    mult = 1 / mintick
    value = ceil(x*mult)/mult
    
f_round_down_to_tick(x, mintick)=>
    mult = 1 / mintick
    value = floor(x*mult)/mult

var float   stopLoss = 101.68

roundedStopLos = f_round_up_to_tick(stopLoss, syminfo.mintick)

if barstate.islast
    label.new(bar_index, high, tostring(roundedStopLos))
