//@version=6
indicator("EMA trend with a daily filter", overlay = true)
len = input.int(21, "EMA length")
fast = ta.ema(close, len)
daily = request.security(syminfo.tickerid, "D", ta.ema(close, len))
plot(fast, "EMA", color.teal)
plot(daily, "Daily EMA", color.orange)
up = ta.crossover(close, fast)
plotshape(up, "Cross up", shape.triangleup, location.belowbar, color.green)
alertcondition(up, "Cross up", "{{ticker}} crossed above the EMA")
var t = table.new(position.top_right, 1, 1)
if barstate.islast
table.cell(t, 0, 0, close > daily ? "Above daily EMA" : "Below daily EMA")
log.info("Close {0}", close)This example runs on Alertsify as written: an input, two EMAs, a daily timeframe, a shape, an alert condition, a table and a log line.
Alertsify's engine is Pine-compatible, written from the language's public behavior. Here is what it runs today.
Not every part of the language is supported yet. When a script uses something we don't run, it stops with a sentence saying what, or runs and tells you what it skipped. Data the chart has no source for reads as na.
Your scripts sit on the same free chart as everything else.
Illustrative examples, not real trades.
Browse indicators other traders have published and add them to your chart, or publish your own script.
