While AFL supports looping ( for , while ), it is rarely needed for standard indicators. Logic is typically handled via logical operators:
Unlike traditional programming languages that process data point by point, AFL is fundamentally . Understanding Array Processing amibroker afl code
Use // to comment on your logic for future reference. Learning Resources While AFL supports looping ( for , while
AFL provides automatic variables:
The example uses the Exponential Moving Average ( EMA ) function to calculate the fast and slow moving averages. When backtesting, verify you aren't referencing future bars
If your strategy generates consecutive buy signals while you are already in a trade, use Buy = ExRem(Buy, Sell); . This removes redundant signals and cleans up your charts.
When backtesting, verify you aren't referencing future bars. For example, writing Close[i+1] introduces a look-ahead bias that invalidates performance testing.
