I was migrating from some previous C++ and Rust () indicators and I noticed the MACD has completely different values to what I expected. I also checked on Yahoo finance and the difference was also apparent. Looking at your implementation, there is no K (multiplier) used - to be fair, I have seen MACD formula's online (inc Wikipedia I think) that do not utilise a multiplier, however a great many MACD implementation do, including TradingView.
