What this script says

Ribbon Multi-Timeframe is a strategy that trades GBPUSD on 15-minute bars.

It uses the indicator "Trend Ribbon" (version 3) as `ribbon`, with `fast` set to 10 and `slow` set to 30.

It calculates `ribbon_4h` as `ribbon.on(bars: 4h)`.

When `ribbon_4h.up` and the close crosses above `ribbon.fast` and `ribbon.strength` is above 0.5, it buys at market, risking 1% of the balance, with a stop 1.5 × the 14-bar ATR from the entry and with a target 2R from the entry.

When `ribbon.up` stops being true, it closes all long trades.
