Strategies FAQ

Can I write in my own editor?#

Yes. A strategy or an indicator is one .py file. Write it anywhere and keep it where you like. Upload a strategy on the Strategy card in Forge, or paste it into the editor here. Tests run in Forge on oathra.app, not on your computer.

How many strategy classes can a file hold?#

One. Its class name is the default display name. See the style guide.

Can a strategy trade more than one symbol?#

Yes. Declare the symbols and read another one with d["GBPUSD"], which has the same attributes as the main series.

When does an order fill?#

At the first real price after the bar it was decided on has closed. See bar close and fills.

Which hooks can a strategy define?#

See write a strategy for every hook and when it runs.

What is FORGE_API for?#

It names the level of the Forge API the file was written for. A file without it, or with a level Forge does not support, is refused.

Why does compute have to be pure?#

It runs once over all the bars. It cannot read the clock, the account or a random number, so it gives the same answer every time.
