Re: [amibroker] Re: Help with Scrip Still not working??

[Terry <MagicTH@xxxxxxxxxxx>]

First, another member suggested using Cross. That is a better method than what I showed so you only get a single Buy condition at the moment it crosses support. Your description says to me you want to Buy when the Price crosses below the Support Level so use:

Buy = Cross(S1,Low);

As to the problem, set your BuyPrice and SellPrice before the Buy signal AND I would use either BuyPrice = Open with Trade Delays = 1 (buy at open of next bar) or BuyPrice = Close with Trade Delays = 0 (buy on the same bar at the close of that bar). If you really want to Buy at your support level (which you can't control) I think simply moving the BuyPrice = S1 before the Buy statement will do it.

Thanks Terry
 I replaced the scrip with this as you suggested

PP = Ref(Avg,-1);
R1=(PP * 2) - Ref(Low,-1);
S1= (PP * 2) - Ref(High,-1);

Buy = S1 > Low;
BuyPrice = S1;
Sell = R1 < High;
SellPrice = R1;

 It stills buys the low or the S1 value. If the S1 value does not 
exist it will buy the low.
So I still need some help.
Thanks Ernie

I am trying to write a backtest to BUY at the Support level S1 and sell when the Resistance level R1 is reached. The codes I have been trying will not BUY at the S1 or Sell at R1. How can I get AB to only buy at S1 when the price has actually traded in that range. I would put in an order to buy that price if touched and sell at R1 if touched. I just can't seem to be able to backtest this. 


PP = Ref(Avg,-1);
R1=(PP * 2) - Ref(Low,-1);
S1= (PP * 2) - Ref(High,-1);

if (S1[0] < Low[0]) 
Buy = 0;
else if (S1[0] > Low[0])
Buy = S1;
BuyPrice = S1;
if (R1[0] > High[0])
Sell = 0;
else if (R1[0] < High[0])
Sell = R1;
SellPrice = R1;

THANKS Ernie
