Buy and sell arrows

["avcinci" <avcinci@xxxx>]

Hi, All:

I've noticed a strange anomaly. After inputting a system formula into 
AA and running a backtest, I right click on a trade and choose 
current trade arrows, and I am able to see the green buy arrow and 
red sell arrow in the price chart. However, if I copy the exact 
formula into guru commentary and press the apply button, I notice the 
buy and sell arrows are moved back one bar on the price chart. If I 
return to AA and right click on the trade and choose current trade 
arrows again, it returns the buy and sell arrows back to their 
original position. Why is this?
