Are there any position limits? OANDA Asia Pacific

Yes, there are position limits—the maximum permitted size (i.e. units, or contracts) of exposure in a single  instrument across OANDA’s sub-accounts. There are also client and trading account limits—the maximum permitted size of exposure in all instruments across OANDA’s sub-accounts.

All limits apply on the client level, which means that the exposures are aggregated across all sub-accounts and the limits are applied to the aggregated exposures.
