Wilder’s Accumulative Swing Index (ASI)
This index has been created by a genius of the trading world, Welles Wilder, the same that created ADX and RSI.
The index is quite straightforward but the application of it requires some knowledge of its principles. I suggest reading Wilder’s bestseller “New concepts in technical trading” (buying this book it’s an outstanding investment already but you can also find PDF’s of it on line).

I don’t know but i am doing something wrong but obvious to others. I download this indicator as a .itf file. I import into PRT using pro screener/set pro screener. All well.
Then i use the Add indicator function to add it to a chart. Boom, the hole chart implodes and gets about 0,5 cm high. Can’t see anything on the chart. I can see ASI indicator. This happen now and then also when importing both indicators and automatic systems. I use PRT version V11.1 – 1.8.0_202 (may 26). So what do i do wrong?

Change the price scale to use “price only”.
Hi.
Thank you so much for helping out Nicolas. At last i found where to set the configuration Price scale “Price only”. I checked the box and poff the price bars chart took over the hole “screen”. But now it is impossible to add the Accumulative Swing Index at all. I can see it in upper left corner but it do not appear under the price chart.
Sorry, but i am learning bit by bit 🙂
