Strategy Not Looping code

[zphinx]

Hi guys,

I'm having trouble with a strategy that kicks off trades using a Bollinger line.

for example

OnBarUpdate=False

If [close] CrossAbove Bollinger [Lower] BarsAgo=0
Buy

If [close] CrossBelow Bollinger [Lower] BarsAgo =0
Sell

The problem occurs when there is an intrabar spike through the line, say price action cross's above the Bollinger line, a Buy trade is placed, but within the same bar it then crosses below the line, the strategy doesn't close out and go short and vice versa when part of the code is kicking off trades from the upper Bollinger line.

I'm using a 7 min chart on the HangSeng.

Any suggestions would be appreciated.

Thanks

Leonie

Within one bar going above the line means a cross above, but coming back down below the line is not a cross below. To determine a cross above/below it uses two data points, the current bar and the previous bar. Just because you are above on one tick and not above on another does not mean a cross below in relation to the previous bar.
