NT syntax help

[ark321]

I've been trying to code this logic for one of the function -


ef ul = SMA( High * (1 + 4 * (High - Low) / (High + Low)), length = 14);
def vc1 = EMA(close(period = Hour) , 12) - ExpAverage(close(period = hour) , 26);
def va1 = EMA(vc1, 9);

def diff = (vc1 - va1); <-- expecting a double value

Can someone help me with the syntax plz?

Hello ark321,

Thank you for your post.

This looks to be in Thinkscript, is that correct?

I've figured out most of the stuff. Only question I've is how do i get high and low values of higher time frame bar (for example 1 hour) inside the lower time frame (for example) 5 min?

Hello ark321,

Thank you for your reply.

You would need to use AddDataSeries() to add the 1 hour (60 minute bar) to your script in the State == State.Configure section of the OnStateChange method:

AddDataSeries(BarsPeriodType.Minute, 60);

You would then need to specify the BarsArray index of the second series when referring to High/Low/Close/Open series for that. The primary series will have an index of 0, the first added series would have an index of 1, the second 2, and so on. So, for example:

EMA(close(period = Hour) , 12) would become EMA(Closes[1] , 12); To refer to an individual Close price of the secondary series, you would use Closes[1][0] to get the close value of the most recent bar.

Considerations for working with multi-series scripts may be found in our help guide here:

thanks a lot. That helps

one other question: if the 2nd series is higher time frame - does Closes[1] gives previous candle's close ( since the current 5 min candle could be inside the current 60 min which is not closed yet)

Hello ark321,

Thank you for your reply.

Closes[1][1] would give you the close of the previous 60 minute bar. Basically it's Closes[BarsArray index][BarsAgo to get the price from].

You'll want to be careful referring to series like High/Low/Open/Close when you're working with multiple data series. For example, if you're wanting to get, say the current close of the primary series, you'd want to make sure you use Closes[0][0] to specify that primary series close is the one you want, not the secondary series. The same would be true for high/low/open, you'd want to refer to Highs[0][0] or Lows[0][0] or Opens[0][0] to make sure you are getting the values from the correct series.

This section of that page I previously linked gives a bit more detail:
