[amibroker] Re: Problems with tracing variable value through exploration...

[Mike]

Try passing a scaler to the _TRACE instead of an array. Since you are 
interested in the most recent value, just use the LastValue function in the 
trace:

_TRACE("sell..." + LastValue(Sell) + " buy..." + LastValue(Buy));

_TRACE("Close..." + LastValue(C));

_TRACE("MovAvg..." + LastValue(MovAvg));
