We’ve been testing trade execution on Binance Testnet and have encountered strict trade limits despite having sufficient funds. Our account holds ~$100K in BTC and BNB, but we can only execute trades of ~$7 per order. We’ve verified that our API key has full trading permissions (canTrade: true), confirmed that our trades follow Binance’s LOT_SIZE and stepSize rules, and ensured all trades meet the $5 USDT MIN_NOTIONAL requirement. Despite this, increasing trade size results in “Account has insufficient balance for requested action” or “Filter failure: LOT_SIZE” errors. We’ve checked for open orders, locked balances, and Testnet-specific restrictions but haven’t found a clear reason why Testnet enforces such a low max trade size. Does Binance Testnet impose hidden per-account trade limits, or is there a liquidity cap affecting larger orders? If anyone has successfully placed large trades on Testnet, what strategies or workarounds did you use?
Could you please share the exact order parameters that cause failures for you, and some more context on why you believe the filter is wrong?
Note that Testnet is much more volatile (e.g., BTCUSDT has low-high range of 17784–84573 over the last 24 hours, while on the real exchange it’s 79939–84199). Some order types use the last trade price to decide on how much of your assets to lock, and this volatility can throw them off.

@Brandono are you buying or selling? Is that for simple LIMIT orders, or something fancier, like MARKET orders with quoteOrderQty? How often do failures happen to you?
You should definitely be able to trade, like, $100 of value most of the time. Unless somebody decides to market-buy $300k worth of BTC and drains the entire order book, leaving only the crazy prices.
Note, however, than Testnet is primarily intended to test API integration. It is not intended for testing trading strategies, etc.
We’ve been placing MARKET orders, specifying the quantity directly (not using quoteOrderQty), and buying BTC and BNB using USDT. Failures happen consistently whenever we try to trade more than ~$7 in value, even though our balance is high. We expected Testnet to allow at least $100 per trade, but any attempt to trade larger amounts results in an “Insufficient Balance” error. Given that Testnet liquidity can fluctuate, could Binance be enforcing a rolling liquidity limit per account, even when sufficient balance is available? Would using LIMIT orders instead of MARKET orders help bypass this issue?
We’ve tested both MARKET and LIMIT orders on Binance Testnet to see if different order types would allow us to bypass trade size restrictions. Despite having over $100K in available balance, our trades are still capped at around $7 per order. We attempted a LIMIT order for BTCUSDT (0.0002 BTC @ 81,000 USDT) and BNBUSDT (0.024 BNB @ 575 USDT), both of which failed with “Account has insufficient balance for requested action.” This confirms that Testnet is enforcing per-account trade limits regardless of order type—the issue is not LOT_SIZE or stepSize, as we are following Binance’s rules exactly. At this point, we suspect Binance Testnet is applying undocumented trade caps per user or dynamically limiting liquidity based on past trade volume. Is there a way to request higher trade limits on Binance Testnet, or are we permanently restricted to small orders?
