[amibroker] EOD RSI backtesting question

[Tim]

When I back test my system which uses end of day data (open, high, low, 
close)and I'm making a buy at open based partly on the RSI indicator, is the 
RSI value correct (in backtest) at the opening? high? low? and close? The 
reason I ask is because my RSI indicator chart only looks like the value at 
close.
