Dear Gurus and seniors,
Need ur help in this.......

I need to run a custom scan (from Analysis > Auto analysis) of shares that have just broken up in MACD / RSI???

Pls explain to me in simple terms as i hve just started using Amibroker and after long time have been able to import the EOD data in Amibroker

Are there any live (FREE) links that update the data??????
