I used np.subtract () where I got the following error.

Cannot convert input [(0, slice(None, None, None))] of type to Timestamp

stock_open=panel_data['Open']
stock_close=panel_data['Close']
row,col=stock_close.shape
movements = np.zeros([row, col])
for i in range(0, row):
    movements[i,:] = np.subtract(stock_close[i,:], stock_open[i,:])

The below line in my code:

movements[i,:] = np.subtract(stock_close[i,:], stock_open[i,:])

gives me the following error.

TypeError: Cannot convert input [(0, slice(None, None, None))] of type to Timestamp

use the below line 

np.subtract(stock_close.values[i,:], stock_open.values[i,:])

or if you're looking for an even better way to do it :

stock_close.values[i,:] - stock_open.values[i,:]
