Hi Racket users, I'm trying to extract some information from a webpage. First attempt is to read the complete page Later i will try to filter the StockPrice and Volume at a certain time The goal is to calculate what direction the StocPrice is moving in multiplied by the number of Stocks that changed owner during vast amounts of time. Like if it was a moving/accelerating mass in fysics and you want to know it's momentum The value of this program is void. It's just for fun.
The first problem I encounter is that reading the webpage stops at the first curly bracket #lang racket (require net/url) (define GLE (get-pure-port (string->url " http://www.tijd.be/beurzen/Societe_Generale.360017048";))) (define readPage (lambda (ticker) (read/recursive ticker))) (define readMore (lambda () (let ([length (pipe-content-length GLE)]) (if (< (file-position* GLE) length) ((display (readPage GLE)) (readMore)) (print 'Finished))))) (readMore) error --> .....ascript>djConfig=. read: unexpected `}' Sorry for the naive code, i'm just a beginner. Thanks in advance Frank
