[amibroker] exploration: displya buy and sell price on same row

[dimension]

How can I display the buy and sell price of an exploration on the same row?  for instance, in the code below, what should “????” be?   bArray = RSI( 5 )<30; sArray = RSI( 5 )>80;   pctChg = ( ValueWhen( sArray, C ) - ValueWhen( bArray, C ) ) / ValueWhen( bArray, C ) * 100;   AddColumn( rsiArr , "rsi", 1.2 ); AddColumn( C , "Buy", 1.2 ); AddColumn( ???? , "Sell", 1.2 ); AddColumn( pctChg, "% Price Chg", 1.2, IIf( pctChg < 0, colorRed, colorGreen ) );   Filter = bArray;     Thanks..
