[amibroker] using indicator in Script for backtesting

["chwinc2000" <chwinc2000@xxxxxxxxx>]

Hello All,

I created a indicator which I called in my script during backtest. 
When I am backtest it it runs extremely slow. I takes forever if I 
try to optimize it.

I think it is because at each bar, I calls the function again and 
again causing massive resource usage. Does anyone know how to access 
it at a specific bar or recode to better use the function.

THanks,
Chris




function numUpDown(periods)
{
  	for(t=0;t<BarCount;t++)
	{
		Value = 0;

		if(t >= periods)
		{
			x = t;
			for(i=0; i<periods;i++)
			{				
				if( C[x] > O[x] )
					Value++;
				else if(C[x] < O[x] )
					Value--;

				if( C[x] > C[x-1] )
					Value++;
				else if(C[x] < C[x-1] )
					Value--;

				x--;
			}
			
		}

		result[t] = Value;

	}

	return result;
}

upDown = numUpDown(10);


Buy = 	AND (UpDown > 0);
BuyPrice = O;
Buy = (Ref(Buy, -1));

Sell = C>ref(c,-1);
SellPrice =  O;
Sell = Ref(Sell,-1);
