There is a new "contract_category": "callputequal" in the contracts_for API response, which has the contract_type CALLE and PUTE. You can use these as your contract type in proposal to convey call equals (higher than or equal to) and put equals (lower than or equal to) options.

I need help with making a copy trading app

Hi,

I have a technical question in regards to the API for buy contract. In the Buy Contract API, the required JSON schema to pass as shown below.

My questions are:

What is Contract_type?

Can you give me a list valid contract type?

I will only trade on Rise/Fall type, where and what value should I pass in if I wanted to buy a rise binary option?

Regards,

Eng Tang

I am currently registered with a virtual account, but will upgrade to real account.

Hello everyone

A few days ago I had integrated the binary api and it was working normally with my platform and the binary integration

based on this documentation

https://developers.binary.com

But three days ago the api has presented problems when trying to buy a contract,

First you must generate the proposal and then the purchase

But ended the sales proposal the following error

"Trading is suspended due to missing market (old) data."

I don't know why this error is generated, sometimes you buy but the error is already recurring.

I thought that it was my code that had the problem but I decided to do it with the base code that delivers binary and also presents the same error

does anyone know why it happens?

let query = {
  "proposal": 1,
  "amount": 20,
  "basis": "stake",
  "contract_type": "MULTUP",
  "currency": "USD",
  "multiplier":"100",
  "symbol": "R_100"
}

ws.send(JSON.stringify(query));
