Alert me in Telegram when a coin moves sharply

Every hour this reads your watchlist from CoinMarketCap and sends one Telegram message for each coin whose price moved further than the percentage you set. Each alert carries the hourly change that set it off, the threshold it passed, the current price and the 24-hour change.

It measures the move over the last hour and runs once an hour, so each run looks at a window the previous run did not. A coin that climbs steadily all day alerts when it moves, not on every run for a day - which is the difference between an alert worth reading and an alert you turn off. 'maxAlertsPerRun' caps how many messages one run can send, so a market-wide swing cannot flood the chat.

A reading that CoinMarketCap does not return raises nothing at all. That is deliberate: an alert fired on a value that was never read is worse than silence, especially at three in the morning. Both of your settings are turned into numbers before anything is compared against them, so a threshold of 12 means twelve and not the text '12'.

Fill in three steps: 'watchlist' with the ticker symbols separated by commas, 'alertChatId' with the Telegram chat to alert, and 'movePercent' with the size of move worth knowing about. Prices are in US dollars, which is fixed rather than a setting, and a symbol has to be inside the top 300 by market cap to be found - raise 'coinsSearched' to widen that.

The alerts report what the market did. They contain no view on what it means and no suggestion about what to do, which is not something a workflow should be handing out.
