AmiBroker for manual backtesting

Hallo everybody,
I'm new AmiBroker user, and I would like to do manual backtesting,
to verify some trading ideas
(you know, initially I prefer to test idea only virtually, to avoid money losses...)

Note: I'm NOT interested to simulate Automatic/Script Trading,
but only manual Buy/Sell order

Now, I've seen the menu Tools / Bar Replay
which allow to repeat the past price candlestick graphs evolution

OK

but now, to make simulation, I need a command to apply the virtual Buy/Sell manual orders on past prices,
and to resume the simulation results

I've seen the menu File / New / Account, but it doesn't allow to simulate trading on past dates

Do you know how to proceed ?
It is necessary to use an external tool, or does AmiBroker have all the necessary stuff?


Any suggestion is welcome

Thanks

Best Regards

Hi,

You have to first add some code (logic) to your chart so that whenever that conditions occurs (is true) on any candle, AmiBroker will show you Buy/Sell signals. To illustrate, add this simple EMA cross code to your chart. To add the code below, simply right click on chart>>Edit Formula and paste code below at the end of your chart.


_SECTION_BEGIN("Sample Trading System");
Buy = Cross(EMA(C,5), EMA(C,12));
Sell = Cross(EMA(C,12),EMA(C,5));

Buy = ExRem(Buy,Sell);
Sell= ExRem(Sell,Buy);

Filter = Buy or Sell;
AddColumn(C, "Possible Candidate for Buy/Sell");

PlotShapes(IIf(Buy,shapeUpArrow,shapeNone), colorBrightGreen, 0, Low, Offset=-15);
PlotShapes(IIf(Sell, shapeDownArrow,shapeNone), colorRed, 0, High, Offset=-15);
_SECTION_END();

Now you can also backtest this code from Analysis>>Automatic Analysis in AmiBroker on any / many symbols at once.

Important Note : This is a sample trading system to show you how things work in AmiBroker - DO NOT trade on the signals shown.

Hope this helps,

Thanks,
CA
