90% of AFLs found over internet have repainting/fake signals. Sometimes you may find an Order placed but no signal in Amibroker Chart. This can happen only if AFL has fake signals. The actual signals triggered by AFL may be different then the signals plot on chart. To check signals, use the AFL plotALLsignals.afl with bar-replay.

Buttons with full functionality for Developers

The Button AFL for Developers allow to use APIBridge with full power. You can send all important values in parameter like strike, expiry for OPTIDX. You can also send custom Stoploss, SquareOff and Trail for Bracket Orders.

How to Use: Provide complete symbol settings for chart symbol on which you apply the AFL. Next, start testing the buttons each time by filling one parameter value at a time. You can also play at the same time with symbol settings. For example, leave Qty blank in Symbol Settings, and change Qty in AFL parameters do dynamically send Qty from Amibroker.

IMPORTANT: Different brokers have different rules for BO/CO. Example, your broker may allow only Limit order in BO, not StopLimit. Or your broker may reject BO if Trail is not provided. To verify these functionalities, you should try placing manual BO/CO order and consult your broker’s API document.

Port: If you change the port in AFL, you also need to change it in APIBridge under Application Settings -> Signal Settings
