While25 is software. It is not a broker, dealer, exchange or investment adviser, and nothing on this site is a recommendation to buy or sell any instrument. Orders you place route to your own brokerage account; While25 never holds funds or securities.

Trading carries risk of loss, including losses greater than your deposit on leveraged products. Backtests and simulations do not predict future returns. Broker and exchange names are trademarks of their owners. We plan to add Coinbase, Binance and Robinhood; you cannot connect them yet.

Risk management system

Risk limits on every order.

You decide how much you can lose in a session, how large an order can be and how many orders you can send. We check every order against those limits before it goes out, whether you place it or your strategy does.

Risk session running: whole-account and derivatives loss limits measuring, beside market watch

Session loss limits.

You set a maximum loss for the whole account and separate limits for stocks, derivatives, crypto and currencies. You enter each one as an amount or as a percentage of your account.

Checks before every order.

Before an order goes out, we check its size, how many orders you have sent and how much money you already have in the market. If an order breaks a rule, we stop it.

A budget for each strategy.

Each automated strategy gets its own money and its own stop button. We never let two strategies trade the same symbol at the same time.

How a risk session works

  • You start a session.

    When you start trading, you start a risk session. We track your profit and loss against every limit until you stop or reset it.

  • We use live prices.

    We measure your loss with live prices, so the number moves as your open positions move.

  • We act at the limit.

    When you reach a loss limit, we block new orders, cancel the orders still waiting and close your open positions.

  • You can always exit.

    A limit never stops you from closing a position or making it smaller.

  • Your code follows the same rules.

    We check orders from your custom strategies the same way we check the orders you place by hand.

  • We log every change.

    We record every change to a limit, with what changed and when.
