Re: [amibroker] Equity(1) modifies sell price ignoring ceil

["Tomasz Janeczko" <groups@xxxxxxxxxxxxx>]

Hello,

ceil may be higher than high, that's why.

Please read the manual
http://www.amibroker.com/guide/h_backtest.html

Quote:
"During back-testing AmiBroker will check if the values you assigned to buyprice, sellprice, shortprice, coverprice fit into 
high-low range of given bar. If not, AmiBroker will adjust it to high price (if price array value is higher than high) or to the low 
price (if price array value is lower than low)"

You can turn that behaviour off using
