Black-Scholes is an accurate model for predicting options prices, Hi, options guy here. I don't think that model has been used for predicting in a long time. It's now used for pricing. Back in the day before computers couldn't run calculations, market makers could arb using these models, but due to the liquidity of the market it's much harder to now. Also, BS assumes european-style options, which is not the case on nearly all options trading. I personally use bjerksund stensland as a model, but just for pricing.
