★ proof, not promises · a complete worked build from the shipping demo

5 answers in. An honest script out.

Demo build 01, exactly as it ships: the filled 5-question card → the script it produced (TV-compiled) → the line that can never be deleted.

The build card → the script it became

1 · Market & timeframe: any liquid chart
    (built on XAUUSD), 1h

2 · The idea (one sentence): In an uptrend,
    a pullback that tags the EMA21 and then
    closes back above it prints a long-side
    marker.

3 · Entry & exit:
  - Entry: trend filter = close above EMA200;
    pullback tag = bar's low touches or dips
    below EMA21; trigger = that same bar
    CLOSES back above EMA21
  - Exit: close crosses under EMA21

4 · Risk & costs: n/a — indicator

5 · Outputs: EMA21 + EMA200 lines, pullback
    markers, state panel, alert on signal

int pullLen  = input.int(21,  "Pullback EMA",
     minval = 1, group = "Engine")
int trendLen = input.int(200, "Trend EMA",

The sentence that makes this pack different

Not validated (mandatory — never delete): "This is a testable draft. It compiles, renders, and follows non-repaint discipline — that is code quality, not evidence of an edge. It has NO out-of-sample validation: the chart you look at while building is in-sample by definition. Judge it on data it has never seen before risking anything." — ends every build report, and cannot be softened.
