Here is an approach from your code with some changes to make it follow
logic to me, and ensure variables are correctly initiated
SetTradeDelays( 1, 1, 1, 1 );
Sell = Cover = 0;
BuyPrice = SellPrice = ShortPrice = CoverPrice = O;
myMA1 = MA(C,10);
MyMA2 = MA(C,100);
Buy = (myMA1 > MyMA2);
Short = (myMA1 < MyMA2);
inBuy = inShort = 0;
ValueAtBuy = ValueAtShort = Null;
for( i = 0; i < BarCount; i++ )
{
if(myMA1[i]<MyMA2[i] AND inBuy AND C[i]>(ValueAtBuy + 0.0010) )
{
Sell[i] = 1;
inBuy= 0;
ValueAtBuy = Null;
}
if(myMA1[i]>MyMA2[i] AND inShort AND C[i]<(ValueAtShort - 0.0010) )
{
Cover[i] = 1;
inShort = 0;
ValueAtShort = Null;
}
if(inBuy) Buy[i] = 0;
if(inShort) Short[i] = 0;
if( inBuy==0 AND Buy[i] )
{
inBuy= 1;
ValueAtBuy = C[i];
}
if( inShort==0 AND Short[i] )
{
inShort = 1;
ValueAtShort = C[i];
}
}
