cTrader ProtoOAUnsubscribeSpotsReq
Stops the live prices of one or more symbols. The definition suggests it as a way to cut traffic, most of all when markets are volatile.
Risk warning: CFDs and spread bets are complex instruments and come with a high risk of losing money rapidly due to leverage. You can lose money on these products, and each provider publishes its own loss figure under FCA rules. You should consider whether you understand how they work and whether you can afford to take the high risk of losing your money. Automated and API trading can amplify losses through bugs, connectivity failures and runaway orders.

Sample
Written by this site from the payload type and fields recorded on this page. It has not been run against a terminal, a server or an account, and the values in it are placeholders. No credential is typed into it: where a field holds one, the placeholder says where it comes from. Nothing is entered on this site.
The three outer keys, clientMsgId, payloadType and payload, are the ones Spotware's page on sending and receiving JSON gives. The sample holds the message's required and repeated fields and leaves the optional ones out. help.ctrader.comchecked
