Hi shunfeng,
Simply place the mq4 file attached to the first place in your MT4 indiors folder. I believe you just want the .mq4 one.
Open a chart and insert it as you would any other indior. Set the BoxSize to 3 and BoxWidth to 3.
Drag the indior box to pay most of the screen and allow it to at least an hour for the data to chart to construct. A new box (a ster really!!) Will shape for each 1/3 of a pip moved (blue up, reddish down).
IMPORTANT: Once, you've got the indior up and producing data in the window, dont change the Timeframe of this chart when the Ticker_Renko_Box indi has built up info or it will begin again from nothing!!
I'll put a few more charts up shortly. Since they're generated in real time you cant test this.
