[amibroker] Getting Portfolio and Single Symbol Equity to match

[ozzyapeman]

In my AA portfolio settings, I have all boxes unchecked. When running a
backtest against a single symbol, shouldn't single symbol equity be
identical to portfolio equity? When I plot both charts, the equity
curves are off by $1-12 or so, fluctuating. While that difference is
obviously not huge, it worries me that they are not absolutely
identical, as larger differences could just as easily pop up.

Any idea why this might be?

fast = Optimize( "fast", 3, 5, 10, 1 );

Buy = Cross( MACD( fast, slow ), Signal( fast, slow ) );
Sell = Cross( Signal( fast, slow ), MACD( fast, slow ) );

Short = Sell;
Cover = Buy;

e = Equity();
Plot(e, "equity", colorGreen, styleLine|styleOwnScale);
