Hello,

Tsl is a global array (declaration line 76) who is populated by a loop in OnCalculate, line 220.

Tsl[0] content is the first occurence of the loop.

I am in the process of converting the Supertrend Filter (Using recursion ver) pinescript to MQL4.
But there is a part I don't understand.

If anyone is familiar with PineScript, could you give me some advice?
What is this expression " Tsl[0] " translated into MQL4?
Or can you give me a simple way to find out the value of " Tsl[0] "?

(Does "Tsl[0]" means current Tsl value?? But it has not been calculated. )

Thank you in advance.

Code: Select all

//@version=2
study("Supertrend Filter",overlay=true)
//
Pd=input(200)
Factor=input(0.9)
//
P = pow(Pd,2)
a = 2/(P+1)
d = abs(close - nz(Tsl[0],hl2))
t = a*d+(1-a)*nz(t[1],d)
src = Factor*nz(Tsl[0],hl2) + (1-Factor)*close
Up=nz(Tsl[0],hl2)-t
Dn=nz(Tsl[0],hl2)+t
//
TrendUp=src[1]>TrendUp[1]? max(Up,TrendUp[1]) : Up
TrendDown=src[1]<TrendDown[1]? min(Dn,TrendDown[1]) : Dn
//
Trend = src > TrendDown[1] ? 1: src< TrendUp[1]? -1: nz(Trend[1],1)
Tsl = Trend==1? TrendDown : TrendUp
css = Tsl > Tsl[1] ? #0080FF : Tsl < Tsl[1] ? #FF0040 : na
plot(Tsl,color=fixnan(css),transp=0)

Thanks for the reply.
Does this mean that Pinescript can get the values regardless of the rows of the calculation results?

Sorry i don't know what is Pinescript, but since OnCalculate event is call on every tick, Tsl is always populated with value.

I could not solve the problem.

The problem is that the calculation results change depending on the number of historical data and the starting candle of the calculation.

If anyone downloaded attached file last time, please stop using it.
The calculation results change depending on the historical bars of each chart. (Even if it is the same currency pair!)
It is not reproducible.


Of course, with TradingView, this problem does not occur.


Sorry for the inconvenience.

hello,
when I add the zero named indicator to the subwindow, it does not remove the title of the other indicator like yours.
I wonder where am I going wrong, could you please explain?
Thanx in advance.

Thank you so much,
Do we have a chance to do the same cleaning on the main chart window?

Just use Kvak's supertrend found here viewtopic.php?p=1295495340#p1295495340 with one of the later versions of my XU-Hybrid found here viewtopic.php?p=1295456155#p1295456155

Play around with the setup and see what works for you.
