I'm having trouble with the arrays aligning when using sc.GetChartBaseData(). I'm testing with historical daily bars. I'm still using UNG and UGAZ for simple tests. It looks like the correct data loads then there are a thousand or so zero's until "sc.ArraySize-1". The last number before the zero's start is the correct close for today. For sc.GetChartBaseData(), shouldn't a negative chart number align today's daily close at array index "sc.ArraySize-1"? Debugging output correctly shows UNG as chart 2 and UGAZ as chart 3 (listed as ChartNum and CNum in the debug output). This is the code I'm using with some debugging: sc.GetChartBaseData((-1 * pStockIndexArray[i].ChartNumber), RemoteBaseData); //sync charts //debug print out array. for(index=0; index < sc.ArraySize; index++) { sprintf(debugstr, "data \"%s\" %d %f", pStockIndexArray[i].Symbol, index, RemoteBaseData[pInputDataIndex][index]); debug_PrintStringToFile(debugstr); } sprintf(debugstr, "High/Low 1: Sym=\"%s\" CNum=%d 0=%f now=%f sc.ArraySize=%d sc.Index=%d", pStockIndexArray[i].Symbol, pStockIndexArray[i].ChartNumber, RemoteBaseData[pInputDataIndex][0], RemoteBaseData[pInputDataIndex][sc.Index], sc.ArraySize, sc.Index); debug_PrintStringToFile(debugstr); //Find high/low code clipped for space. What matters is above this line of code. sprintf(debugstr, "High/Low 2: Sym=\"%s\" CNum=%d high=%f low=%f PO=%f Mul=%f bars=%d sc.ArraySize=%d sc.Index=%d", pStockIndexArray[i].Symbol, pStockIndexArray[i].ChartNumber, high, low, pStockIndexArray[i].PriceOffset, pStockIndexArray[i].Multiplier, bars, sc.ArraySize, sc.Index); debug_PrintStringToFile(debugstr); Here is the debug output. The "data" lines are the arrays printed out at the index number.
