you have to understand the kind of guy who works in a bucket-shop who does pump&dump/boilerroom shit.. they're a 'unique' kind of person. they're loudmouths and they lie and exaggerate everything. they're usually broke as hell for a long time, but some of their friends make a lot of money, so as soon as they hit a big commission check, they blow their money and live like white rap stars until they're broke again and when the money's gone, they'll tell stories and relive their 'glory days', except they'll embellish it x10.
there's a reason they're working in a fucking bucketshop in the first place, and not working for a respectable firm as a broker or prop trader... 90% of these guys are losers and bullshit artists. 90% have no long-term goals or investment strategy.. they're just hustlers and con-men. and if you've ever been to prison (or rehab), you know the stories that hustlers and con-men tell that tell that glorify their past lifestyle.
is the movie true? sorta... take a little bit of truth and embellish it. Jordan doesn't do that just with the movie, he does it with everything he does and everybody he talks to from the dude who takes his order at Burger King, to the lady interviewing him for 60Minutes. he's telling a story he wishes was true.. how it would've turned out in his mind.
