23 pairs, 5 pairs at 100x, November 19 at 15:00: Binance is increasing the order quantity increments for 23 spot trading pairs. After 15:00 on the 19th, orders submitted using the old quantities will be rejected outright. I checked the original announcement and found that more than just the two LUNC pairs are getting a 100x increase.
One thing first: before writing this, I checked the original announcement, and found that the figures in the 13:30 article were wrong. It said 21 pairs would have their increments multiplied by 10 and 2 pairs by 100, but the actual figures are 18 pairs at 10x and 5 pairs at 100x. DOT, FIL, and NEXO also go from 0.01 to 1. The 13:30 article has already been published and can’t be changed, so the correct figures are in this article. Follow this one before the 19th.
This post isn’t about the rules themselves—that was covered in the 13:30 post. This one is just about the 5 things you need to do before the 19th. Just follow the steps.
Step 1: Check the list and see whether you have any of these 23 pairs
Of the 23 pairs, 21 are against Bitcoin: ADA, ARB, AVAX, BCH, DOT, ETH, FET, FIL, INJ, LINK, LTC, NEAR, NEXO, PAXG, SOL, STX, SUI, UNI, WBTC, WLD, and XRP; the other 2 are LUNC/USDT and LUNC/USDC. The 5 pairs with 100x step sizes are DOT, FIL, NEXO, LUNC/USDT, and LUNC/USDC; the remaining 18 pairs have 10x step sizes. Focus on three types of orders: ones you currently have open, ones running through grid and recurring-buy strategies, and parameters hard-coded into bot strategies.
Step 2: Leave existing open orders alone; new orders must follow the new step sizes
The original announcement is very clear: orders placed before 15:00 on the 19th will continue to be matched using the old step sizes. They won’t be changed or canceled. The real issue is new orders placed after 15:00 on the 19th—if the quantity isn’t a multiple of the new step size, the system will reject the order outright. So there’s no need to rush to cancel orders, but check the quantity before placing any orders after the 19th.
Step 3: Recalculate quantities using the new step sizes and remember these three examples
ETH/BTC: 0.0001 changes to 0.001, so order quantities must be multiples of 0.001. If you used to place orders for 0.0005 ETH, you won’t be able to after the 19th—change it to 0.001 or 0.002. DOT/BTC: 0.01 changes to 1, so orders must be in whole coins; an order for 0.5 DOT will be rejected outright. LUNC/USDT: 0.01 changes to 1, making 1 LUNC the minimum increment. All orders with fractional quantities need to be changed.
Step 4: If you use APIs or bots, fetch the latest step sizes before the 19th
Binance has said that the step-size information in the API will also change. You can get the latest information by calling GET /api/v3/exchangeInfo. Update any step-size parameters hard-coded in your bots, grid strategies, or recurring-buy scripts to the new values before the 19th. After updating, run a small test order and make sure it goes through before running everything at full scale. The easiest way to get caught out is to leave the old step size in your strategy and have a batch of orders rejected when the market opens on the 19th.
Step 5: Keep track of these two times on the 19th
At 15:00 on November 19, the new step sizes for the 23 pairs take effect. Earlier that same day, from 09:00 to 11:30, the BITOUSDT contract will undergo a contract-value adjustment. Contract trading will be suspended during that period, unfilled orders will be canceled, and positions will be closed automatically. Don’t handle spot and contract trades in the same window; take care of contract orders in advance.
While you’re at it, make a note of these three dates and times:
November 19, 09:00–11:30: BITOUSDT contract-value adjustment; trading suspended, orders canceled, and positions closed automatically.
November 19, 15:00: New step sizes take effect for the 23 spot pairs.
November 20: The seven-day review period for MANTRA’s suspension of unbinding ends. I mentioned it at 13:00 and 16:00—make a note of it too.
Three things to watch out for:
First, don’t focus only on LUNC. DOT, FIL, and NEXO also have 100x step sizes. The 5 pairs with 100x step sizes are the easiest to trip up on.
Second, don’t assume existing open orders will be changed. They won’t. Orders placed before the 19th will be matched using the old step sizes; just don’t use old settings to place a batch of new orders around 15:00 on the 19th.
Third, don’t confuse step size with price. This change affects the minimum increment for order quantities, not the minimum price increment. It doesn’t affect the direction of coin prices, so don’t adjust your positions because of it.
My take: This adjustment doesn’t change the value of any coin or the direction of buying and selling. The only real risk is making an operational mistake—having an order rejected after the 19th because you used the old quantity, or getting a batch of errors from your bot. So it’s not worth adjusting your positions over this, but it is worth spending 5 minutes checking your grid and bot settings. There are two things that would change my view: if Binance issues a follow-up announcement after the 19th expanding the scope, or if any pair sees unusual volatility due to the step-size change. If either happens, I’ll write another post.
I’ll also share my personal view: this is the third rule change in three days—leverage was cut in half on November 10, MEXC’s supply was cut off on November 12, and now this step-size change. Binance is clearly tightening things up this week. The only thing retail traders can do is avoid being the person whose order gets rejected on the day the rules take effect.
Have you ever had an order rejected by an exchange for not meeting the step size? What happened to that order afterward?
Follow me. I’ll check the details as soon as the changes take effect at 15:00 on November 19, and I’ll be the first to break down Binance’s next rule change too.
