input price = close;

input length20 = 20;
input length40 = 40;
input length200 = 200;
input displace = 0;

plot SMA20 = Average(price[-displace], length20);
plot SMA40 = Average(price[-displace], length40);
plot SMA200 = Average(price[-displace], length200);

SMA20.SetDefaultColor(GetColor(1));
SMA40.SetDefaultColor(color.red);
SMA200.SetDefaultColor(color.yellow);

Try this

input price = close;

input length20 = 20;
input length40 = 40;
input length200 = 200;
input displace = 0;

#new code
input ShowTodayOnly = yes;
def Today = if GetDay() == GetLastDay() then 1 else 0;
# end

plot SMA20 = if ShowTodayOnly and !Today then Double.NaN else Average(price[-displace], length20);
plot SMA40 = if ShowTodayOnly and !Today then Double.NaN else Average(price[-displace], length40);
plot SMA200 = if ShowTodayOnly and !Today then Double.NaN else Average(price[-displace], length200);

SMA20.SetDefaultColor(GetColor(1));
SMA40.SetDefaultColor(color.red);
SMA200.SetDefaultColor(color.yellow);
