I need for this all to be 1 transaction for the user so they call the contract from my website and metamask,...

I want to develop solid, real-world skills in crypto trading and I’m starting from a beginner’s standpoint in technical analysis. I can read basic candlestick charts but that’s where my confidence ends. I need a seasoned trader who can walk me through the core concepts of technical analysis—interpreting price action, spotting reliable patterns, and understanding indicators such as moving averages, RSI, MACD, and Fibonacci levels in the context of Bitcoin, Ethereum, and the major alt pairs I follow on Binance and Bybit. My goal is to progress from theory to practical application, so live screen-share sessions on TradingView (or a comparable charting platform you prefer) are essential. I’d like you to demonstrate how you build a trade thesis, set entries and ex...
