In latest version of amibroker reverse is a reserved function. Try to change the to reverse1 or something like that. I only use amibroker 5.5 and there is no such issues.
Major Contributors of last Friday's BN up move was by Federal bank, Bankbaroda, PNB, SBIN & Yesbank. Canbk is just started uptrend. But market is unpredictable lest's wait and see.
