Usage

binance-oco

Market and limit buy orders

Place a market buy order for 1 BNB:

binance-oco -p BNBBTC -a 1 -b 0

For non market orders, binance-oco determines whether to place a limit or stop-limit buy order based on the current price.

eg. If the current BNBBTC price is at or above 0.002 BTC, place a limit buy order for 1 BNB @ 0.002 BTC. If the current BNBBTC price is below 0.002 BTC, place a stop-limit buy for 1 BNB with stop price @ 0.002 BTC.

binance-oco -p BNBBTC -a 1 -b 0.002

If the current BNBBTC price is below 0.002 BTC, place a stop-limit buy for 1 BNB with stop price @ 0.002 BTC, and limit price @ 0.0025 BTC.

binance-oco -p BNBBTC -a 1 -b 0.002 -B 0.0025

Limit prices for stop-limit orders

If specific buy/sell limit prices aren't specified with the -l or -B/-E options respectively, binance-oco sets the limit price for stop-limit orders to emulate a stop market order ie. buy/sell at market price once the stop price has been hit.

To achieve this, limit prices are calculated as follows:

• Buy limit price set to maximum allowed by available balance and Binance PERCENT_PRICE trading rule
• Sell limit price set to minimum allowed by Binance MIN_PRICE, MIN_NOTIONAL and PERCENT_PRICE trading rules

Binance will still fill orders at the best price available, but order details may show a very low sell or very high buy price.

See How to use Stop-Limit Function for information on stop-limit orders, and the Binance Trading Rules for details on Binance trading rules.

Stop-limit and limit sell orders

Place a stop-limit sell for 1 BNB @ 0.001 BTC:

binance-oco -p BNBBTC -a 1 -s 0.001

Place a stop-limit sell for 1 BNB with stop price @ 0.002 BTC, and limit price @ 0.001 BTC.

binance-oco -p BNBBTC -a 1 -s 0.002 -l 0.001

Place a limit sell for 1 BNB @ 0.003 BTC:

binance-oco -p BNBBTC -a 1 -t 0.003

Conditional sell orders

Place a buy order for 1 BNB @ 0.002 BTC. Once filled, place a stop-limit sell @ 0.001 BTC:

binance-oco -p BNBBTC -a 1 -b 0.002 -s 0.001

Place a buy order for 1 BNB @ 0.002 BTC. Once filled, place a limit sell @ 0.003 BTC:

binance-oco -p BNBBTC -a 1 -b 0.002 -t 0.003

One-Cancels-the-Other (OCO) sell orders

Place an OCO sell for 1 BNB with:

• stop price @ 0.001 BTC
• limit price @ 0.003 BTC

binance-oco -p BNBBTC -a 1 -s 0.001 -t 0.003

Place a buy order for 1 BNB @ 0.002 BTC. Once filled, place an OCO sell for 1 BNB with:

• stop price @ 0.001 BTC
• limit price @ 0.003 BTC

binance-oco -p BNBBTC -a 1 -b 0.002 -s 0.001 -t 0.003

Place a buy order for 2 BNB @ 0.002 BTC. Once filled, place:

• an OCO sell for the scale out amount of 1 BNB with:
  • stop price @ 0.001 BTC
  • limit price @ 0.003 BTC, and
• a stop-limit sell for the remaining 1 BNB @ 0.001 BTC

This process is referred to as 'scaling out' of a position.

binance-oco -p BNBBTC -a 2 -b 0.002 -s 0.001 -t 0.003 -S 1
