OPEN-SOURCE SCRIPT
ST + EMA [BTCUSD]
Delta Exchange embeds your strategy_id inside the Webhook URL itself when they generate it for you. Putting strategy_id in the JSON body sends the request to the wrong endpoint — Delta's router can't find it, hence the 404. The correct JSON body has only 4 fields, no strategy_id.
🔴 Root Cause 2 — qty with quotes → rejected by Delta
Our previous JSON had "qty":"{{strategy.order.contracts}}" (quoted = string). Delta's official format is "qty": {{strategy.order.contracts}} Delta Exchange India — no quotes, making it a JSON number. Delta's API validates the type and rejects strings.
🔴 Root Cause 3 — Decimal qty from percent_of_equity → rejected by Delta
The strategy was using default_qty_type=strategy.percent_of_equity, which calculates fractional contract sizes (e.g. 0.023). Delta Exchange requires order quantities to be whole numbers — decimals like 0.02 or 1.5 are rejected. Delta Exchange Changed to strategy.fixed with default_qty_value=1.
