Maximum price for BUY contact and price proposal issue
I am new to Binary.com and I have a couple of doubts:
- I want to 'buy' a contract (CALL) but I want to get in the market only if the price is below a certain value.
I want to CALL EUR/USD but only if the price is below 1.1123.
How to define the maximum price in the 'buy' contract? I saw something in the documentation:
Maximum price at which to purchase the contract, or '0' for 'buy at market
but if I put '0' I get a weird error (price moved too fast from USD 0.00 to USD 1.00) and any other value I put I buy at market.
Can you please answer me with an example in JOSN format for me to try?
- If I place a price proposal and than use its reference for the 'buy' contact, I sometimes get the error: price moved too fast since price porposal subscription (something like that). What are the conditions under which this error is thrown?
