SRI (Super Renko Indicator) for Amibroker (AFL)
DOMINATOR about 16 years ago Amibroker (AFL)
A type of chart, developed by the Japanese, that is only concerned with price movement; time and volume are not included. It is thought to be named for the Japanese word for bricks, “renga”. A renko chart is constructed by placing a brick in the next column once the price surpasses the top or bottom of the previous brick by a predefined amount. White bricks are used when the direction of the trend is up, while black bricks are used when the trend is down. This type of chart is very effective for traders to identify key support/resistance levels. Transaction signals are generated when the direction of the trend changes and the bricks alternate colors.

not workin error
Read the description i mentioned it there. Is it the same as that one?
no its working just save and change the parameters
what parameters need to changed
i am using amibroker 5.2
Dear,
aplusads,
I changed " Method calculation volatility ", to 1. from parameter window.
It is atleast showing graph!
But don"t know is it a right setting ?????
Will somebody explain it ?
cnb
but how can use plese explain
actually SRI is working better but for scrip quote greater than 1000 the diplay is gone and range out os subscript error creeps.
how to rectify this error
There is an error in Block # 5. How to fix. What parameters need to change. Pls suggest.
Code was for old Amibroker
