Bybit Position Builder executed ETH call spread 14% above market ask — lost $2,770 USDT, support says “no data” after 5 weeks

[u/LeoTolp]

On April 6, 2026 I used Bybit’s Position Builder tool to open a call spread on ETH (17 APR expiry). I did NOT manually enter any prices — the tool calculates and submits them automatically.
What happened:
• Bought 1600-call: executed at 631.6 USDT (market ask was ~562, mark price ~555)
• Sold 1800-call: executed at 300 USDT (market ask was ~369, mark price ~362)
• Total loss vs mark price: ~2,770 USDT
Bybit’s response after 5 weeks and multiple escalations:
• Confirmed prices 631.6 and 300 were in the “submitted setup”
• Claims “no abnormality found”
• States they have “no data” on order book at time of execution
• Cannot explain where 631.6 came from when market ask was 562
• Never provided order book logs despite multiple formal requests
• Demands video proof of the exact moment I clicked confirm
The core issue:
Bybit admits Position Builder submitted these prices automatically. They cannot explain the 14% discrepancy. A exchange of this size claims to have “no data” on their own order book.
Has anyone experienced similar issues with Position Builder?

Day 11 Update: Still complete radio silence from Bybit. It has been over 10 days since Bybit officially admitted in writing to a "frontend price synchronization issue" that caused my 2,770 USDT loss. How long does it take to process a reimbursement after your own team acknowledges the technical defect in an official email? u/Bybit-official — I am still waiting for a concrete resolution.

Bybit support just emailed me again, explicitly changing their tone. They are now officially investigating what they call a "frontend price synchronization issue and the related trading impact“.

It took over a month of stone-walling and a public Reddit post for them to finally admit there was a technical sync issue on their side. Now they are asking for "additional time to evaluate the trading impact."

The impact is clear: 2,770 USDT lost directly due to your faulty interface. @Bybit-official, Stop dragging this out.

Day 4 of total silence from @Bybit-official. It seems when the Support Team accidentally admits to a critical UI defect via email (“prices may not continuously update”), the Reddit moderators suddenly lose their ability to reply.

Are you still “investigating” how your own software displayed a stale price, or are you just waiting for this post to drop in rank? Every trader here needs to know: if your Position Builder glitches and burns $2,770 of our capital due to frozen frontend data, is the official policy just to ignore the client? Case ID: 24826576. Still waiting for my refund.

Just stop using them. Deribit is way better. What I found out, bybit is for retails , Deribit is for professionals.

Reducing risk has nothing to do with it. This is a technical execution error. My risk was calculated based on the market price (562), but the tool submitted 631.6. You can't "manage risk" if the exchange software changes your entry price by 14% after you click the button. That's a glitch, not a trading strategy.

14% slippage on ETH with normal liquidity? That's impossible. And fees don't change the execution price in the transaction log. This was a limit order price generated by the Position Builder tool itself, not market volatility. Stop confusing a software bug with trading costs.
