How to manage repainting signals in Amibroker?

You may face problems if, Amibroker settings are not correct or, Your AFL has errors. All these problems such as
Signal in Amibroker but no order placed
Order placed but no signal in Amibroker
Too Many Orders Placed From Amibroker
Wrong price sent in order
are due to only two problems: wrong amibroker settings, or wrong afl

Note that all Amibroker related issues are independent of APIBridge.
You can close APIBridge, and use only Amibroker to solve problems.

99% of AFLs available on internet have repainting signals. Many a times one may see that a buy / sell signal appears on the chart, and vanishes before the completion of the candle.

To check repainting, you need to bar-replay with minimum time interval. In this example, I have bar-replay with 1-min time interval but the chart time frame is 15-minute.

Also another problem is that signal does not appear on current candle, but appears after candle completion.

The solution to both these problems is to change parameter Trade Intrabar? Candle Completion.

Some badly programmed AFL show arrow on chart, but do not have buy-sell signal. See this AFL. It shows perfect arrows on bar-replay. But there is no order placed.

To find such bad AFLs we add the code from plotAllsignals.afl
