Hi I am new to quant connect and writing a small algorithm within a period I have identified to see how I could DCA-ing into a position monthly would perform. The DCA part is working and it is buying as per the limit I have set, 

However, I am super confused as to why my portfolio cash is increasing as I buy more, shouldn't it be decreasing? Am I missing something here? Any help is appreciated. Thank you
