A real example.

This is a real run of the importer. The result compiles. It read 11 lines: 6 carried over exactly, 6 were adapted, and 2 came back as choices for you.

Stops written as Ask - 250 * Point carry over literally. They read better, and survive gaps better, as distances: stop: 250 points.

How to move a script.

  1. Paste or upload

    Open the Terminal, choose Import, and paste your code or pick the file.

  2. Read every note

    Each line is marked exact, adapted, or your call. Settle every “your call” before you go on.

  3. Read it back, then test

    Check the plain-English description against what your old script did. Then run a test.

What you gain.

It reads itself back

The compiler writes out what the script does in plain English.

Units are real

Percent, pips, R and money are types. Mix-ups are caught before anything runs.

One script everywhere

The same file draws, tests, alerts and trades.

Always read an import before you run it. No converter is perfect, and some shapes of code import better than others. Other platforms leave things unsaid that AlgoBarsX makes you state, such as the market, the bar size and the trade size. Compare the plain-English description with what your old script did, and test before you deploy.

Good questions.

Will every script convert cleanly?

No. Simple, common shapes convert best. An import that does not compile says so, and every changed line carries a note. Always read the result.

Do I lose my original?

No. Your old script is untouched. Lines that needed a choice keep the original as a comment.

Is it free?

AlgoBars is $0 a month with no card. Credits pay for AI, tests and auto trades.
