Upcoming API changes for contract barrier handling

Raunak · May 2019

Currently, the proposal and proposal_array API calls accept 0 as the barrier input. Internally, this is mapped to a valid barrier.

We plan to remove this internal mapping and all 0 absolute barrier will be rejected with the error Barrier cannot be zero. The API still supports zero relative barriers (E.g.+0.00 or -0.00) as input.

Before the change, this request will be accepted:

{
  "proposal": 1,
  "amount": "100",
  "basis": "payout",
  "contract_type": "CALL",
  "currency": "USD",
  "duration": "60",
  "duration_unit": "s",
  "barrier": "0",
  "symbol": "R_100"
}

After the change, this request will be rejected with the following error:

{
  "echo_req": {
    "amount": "100",
    "barrier": "0",
    "basis": "payout",
    "contract_type": "CALL",
    "currency": "USD",
    "duration": "60",
    "duration_unit": "s",
    "product_type": "basic",
    "proposal": 1,
    "symbol": "R_100"
  },
  "error": {
    "code": "ContractCreationFailure",
    "details": {
      "field": "barrier"
    },
    "message": "Barrier cannot be zero."
  },
  "msg_type": "proposal"
}

These changes will be effective after 27th of May 2019.
