Prompt mode

How it works

Prompt mode is part of the Custom strategy in the Studio. Instead of building rules condition by condition, you describe the idea in a sentence or two. Zolva's strategy writer turns it into ordinary Custom rules, which you can read, change and backtest like any rules you built yourself.

1. Describe the idea. Say when to buy and when to sell, in any language, in 10 to 600 characters.
2. Generate rules. The writer answers with buy rules, sell rules and, if you asked for them, a take profit or a max holding time.
3. Check and edit. The rules appear in the editor below the prompt and the backtest updates at once. Change anything you like before you launch.

An example

“Buy big tech after a sharp drop, when the price is unusually low for the last two days. Sell once it recovers to its average, or after 3 days.”

could become:

The exact rules can differ from run to run. What counts is the version you see in the editor, because that is what the agent will run.

Writing a good prompt

• Say both sides. When to buy and when to sell. If you only describe the buy, the writer has to guess the exit.
• Use numbers when you have them. “Up more than 3% in a day” is clearer than “rising fast”.
• Stay within hourly prices. Rules can only use the indicators listed in Strategies: price, averages, highs and lows, change, z score and RSI, over periods of a few hours to 3 days.
• Leave out sizing and stop losses. Which markets to trade, the max per token and the stop loss are set with their own controls in the Studio.

Notes for the AI co-pilot

Some ideas cannot be written as price rules, such as “avoid buying before earnings” or “be careful outside US market hours”. The writer keeps those as notes. If the agent has the AI co-pilot turned on, the AI reads these notes every time it reviews a trade. Without the co-pilot, notes have no effect.

Cost and limits

• The writer uses Claude Haiku 5.5 and is paid from your AI credits. One generation usually costs well under a cent, and the welcome credits cover it.
• Each account can generate 10 times per 24 hours.
• If you are out of credits, you can still build the same rules by hand.
