If you see this message, it means your Symbol Settings are wrong. The Bridge needs some essential information for order placement.
INPUT SYMBOL: this should be same as your chart symbol in TradingView, Amibroker, MT4 etc.
If you accidentally add a character or do not provide the same symbol as in your Chart, this error will come.
Instrument Name: If you specify an Instrument Name in the signal, you need to provide it correctly in Bridge also. However, you can also leave Instrument Name blank (null) in Signal, to avoid matching with Settings. Similarly for Strategy Tag – if specified in Signal, it should also match with Symbol Setting.
StrategyTag – (1) You can send null/empty strategy tag in signal if you are not using multi-strategy (2) If you specify strategy tag in Signal, it should match with tag given here also.
Note: Order type, Qty, Product Type; in Symbol Settings always over-ride order type in Signal. If you want to dynamically send these in Signal, leave it blank in Symbol Setting.
Input symbol for Nifty is NIFTY in MT4.
Still API Bridge says symbol settings not found.
What’s wrong?
Please also check for strategy tag- you can set in MT4 via parameters window.
