Hi friends
I have a small problem with renko chart.
Often renko chart comes blank in Amibroker.
-----------------------------------------------------------------
ERROR 10
Array subscript out of range.
you must not access array elements outside 0 .. (Barcount-1) range.
------------------------------------------------------------------
Fed up with this problem,new traders stop using RENKO chart.
The idea here is find a small fix and get rid of the problem using addition of a small code line.
It may look a cilly thing but it saves big hassels and makes life easier so that one can go on testing renko chart if it suits or not.
I dont mind finding right brick size by trial and error when I am not trading.
Once I find right bricksize,then I like to put the code line that makes the afl to create renko chart with specified brick size setting the moment i select that symbol.
The code line for single symbol is as follows.
IIf( "ticker"== ParamStr(" ticker","NIFTY14JAN6200CE"),brick =2,0);
IIf( "ticker" == ParamStr(" ticker","SILVERM14FEBFUT"),brick =20,0);
IIf( "Ticker"== ParamStr( " ticker", "LT"),brick =2.4,0); //uses 2.4 as brick size
===========================
I can use only one code line at a time. it works for that sym,bol or any symbol having sama range of brick size setting.
When symbol changes from a stock having brick=2 to a commodity having brick=20,I like the code line to make a smooth transition to deliver new chart.
without manual intereference during trading hours.
suppose i have 10 favourite symbols and their specific brick size values, how can I write these individual code lines together in one line?
Something like
=======================================================
chart afl here
========================
Hope somebody can help link the code lines for single symbols together to get a trouble free renko chart as we change symbol. we need to use comma or OR etc for linking the code lines of 10 symbols into one code line.
------------------------
why Renko chart? becoz it minimises noise and points out trend clearly.
thanks
