I’ve come across all or none orders on various trading platforms, but I’m not clear on their functionality.
Are they only for big trades, or do they serve additional purposes? Just trying to grasp how they operate before using them.
They’re okay for forex but not really needed. Most pairs have good liquidity anyway.
All-or-none orders execute completely or get canceled, with no partial fills. They’re useful when exact position size is critical for your strategy. For example, if you want 1,000 shares but only 300 are available at your price, the entire order is canceled instead of accepting a partial fill. Most retail traders typically don’t require these orders. They’re more beneficial for larger positions where receiving fills in parts can disrupt your risk management or when trading illiquid stocks that may offer slow fills throughout the day.
All-or-none orders ensure that your entire order is executed or it’s completely canceled, avoiding partial fills.
These orders are especially useful for trading illiquid pairs where consistent fills are uncertain.
They help you avoid awkward position sizes that occur when orders only partially fill.
Avoid them. Better with partial fills.
I’ve used these trading weird exotic pairs during Asian hours. Liquidity was so thin I’d get random partial fills that screwed up my position sizing.
Downside? Your order can sit there forever if there’s no volume at your price. I’ve had orders expire unfilled because the market moved before enough sellers showed up.
Most brokers charge the same commission for all-or-none vs regular orders. But some platforms have weird rules about how long these stay active.
For major pairs like EUR/USD or GBP/USD, you probably don’t need them. Liquidity’s usually deep enough that you get filled fast anyway.
