Hello josef,
u hv understood the difference between MaxTrade and investment tradess correctly. Max trades are intraday trades where u get exposure upto 10 times ur margin; but they will be automatically squared off after 3:15 pm if u hv not squared them urself. inorder to sq off Max buys u hv to use max sell not the usual sell buttons and vice versa. during quick intraday trade this may sometime cause confusion and mistake' at least it has done in my case. hence be careful. all other trades are termed investment trades. moreover in case of max trades u can use bracket orders and tsl orders which u cannot do with invetment trades.
