A good free crypto screener lets you filter many coins at once by RSI and MACD on the timeframe you trade, shows when each signal happened, and lets you open the chart straight from the results. Several free options exist, including TradingView's screener and Hunt4Coin's scanner; check which coins and timeframes each one covers before relying on it.
TWAP means time-weighted average price.

No code is needed unless you want orders to update automatically through an API.
