I was wondering when investopedia was going to start making videos about Nadex. Investopedia has quietly influenced investors to trade on Nadex for some time on the investopedia website. Nadex concept is great "even tho binary options were out before Nadex" but their strikes are garbage. Their options strikes are almost pure gambling (intraday). I've traded Nadex for years. They use Black Scholes model with a twist I thought their options were similar to VEGA but idk. Goodluck
