Hi,is there any way to check the data integrity of a list of stocks?

I noticed that some symbols from Yahoo have huge gaps in price early on,and I am only catching some of the bad data when I run a backtest and see MAE
over 80 percent..How does QS check the stock symbols for issues like this?

Trading financial instruments, including foreign exchange on margin, carries a high level of risk and is not suitable for all investors. The high degree of leverage can work against you as well as for you. Before deciding to invest in financial instruments or foreign exchange you should carefully consider your investment objectives, level of experience, and risk appetite. The possibility exists that you could sustain a loss of some or all of your initial investment and therefore you should not invest money that you cannot afford to lose. You should be aware of all the risks associated with trading and seek advice from an independent financial advisor if you have any doubts.
