What this script says

Turtle Channels is a strategy that trades XAUUSD on daily bars. It adds up to 4 entries in the same direction, keeps at least 500 points between entries and stops trading after a 20% drawdown.

You can change 3 inputs: `entry_length` (default 20), `exit_length` (default 10) and `unit_risk` (default 0.5%).

It calculates `entry_channel` as the Donchian Channels (length `entry_length`) and `exit_channel` as the Donchian Channels (length `exit_length`).

When the close crosses above the previous bar's `entry_channel.upper`, it buys at market, risking `unit_risk` of the balance, with a stop 2 × the 20-bar ATR from the entry and tagged "turtle".

When the close crosses below the previous bar's `exit_channel.lower`, it closes all long trades tagged "turtle".

On the chart, it plots `entry_channel.upper` and `exit_channel.lower`.
