# Trader is not buying — all possible causes

> Discover why your trader is not buying new positions: insufficient balance, no credits, unconnected API or a reserved amount that is too large.

If your trader is not buying new positions, it always means that one or more of the required criteria are not met. Below you find all possible causes at a glance, so you can quickly find out what is happening in your situation.

<Note>
  With the **BBT strategy**, the trader only buys at the **start of an upward trend**, not during an already ongoing rise. So it is possible for the price to rise while the trader does nothing: that is intentional and correct behavior. The **Updown strategy** has different buy moments based on price ranges.
</Note>

## Possible causes

<Accordion title="1. Buy moments of the BBT strategy">
  The BBT strategy works according to a fixed format: the trader **only buys at the start of an upward trend**, provided that within the set bandwidth (trader setting **"Min. percentage between buys"**) no other comparable transaction is open **and** enough euro balance is available at the exchange.

  **During a price rise, the BBT strategy does not make new purchases.** Wait for a new buy moment at the start of the next trend.
</Accordion>

<Accordion title="2. Insufficient euro balance at the exchange">
  The trader needs at least **€ 25** of free euro balance on your exchange account to place a transaction.

  Check your balance at the exchange. If your balance is lower than € 25, the trader cannot buy until you top up or an existing position is sold and the balance frees up.
</Accordion>

<Accordion title="3. No credits available in BBT">
  BBT uses credits to cover the platform services. If your credits balance is depleted, the trader stops trading.

  Go to **Settings → Credits** in your BBT account and add credits. As soon as the balance is topped up, the trader automatically resumes its work.
</Accordion>

<Accordion title="4. API not connected or incorrectly connected">
  If the API key is not correctly connected or is inactive, the trader has no connection with the exchange and cannot place orders.

  Check the status of your API connection through **Settings → Exchanges**. Is the exchange inactive? Then consult the [API key problems](/en/errors/api-key-problems) page for the solution.
</Accordion>

<Accordion title="5. Reserved amount set too large">
  If you have entered a reserved amount in the exchange setting that is greater than or equal to your free euro balance, **no free balance** is available for new purchases.

  Go to **Settings → Exchanges** and lower the reserved amount, or wait until enough balance frees up from a sale.
</Accordion>

<Accordion title="6. Price ceiling reached">
  If the current price of the coin is **above the set price ceiling**, the trader does not make new purchases. This is a deliberate protection to prevent purchases at historically high prices.

  Check the price ceiling setting in your trader. Adjust it if the situation justifies it.
</Accordion>

<Accordion title="7. Maximum number of open buys reached">
  If the set maximum for simultaneously open buys has already been reached, the trader does not make new purchases, not even at a new buy moment.

  Increase the maximum through the trader setting **"Maximum open buys"**, or wait until existing positions are sold.
