There are negative aspects about Tiger that cannot be conveniently talked about in sponsored articles. Since this is not a sponsored article, I can freely talk about them here.
The top reason that keeps me wary of using Tiger as my main broker is that Tiger is still a young company at this stage. It was set up in 2014 and managed to become profitable this year (2020). Since funds are held in custody, having a financially strong broker with very low probability of going bust is important. Tiger uses DBS as custodian. This makes me feel safe that my assets are protected if Tiger goes bust. However, even if funds can be recovered 100% later, there is the issue of the funds being temporarily frozen while the bankruptcy issues are being sorted out. If the securities are frozen, the investor/trader cannot sell. If he cannot sell, he cannot manage his risks. This is fine for bonds and index funds/ETFs which the investor is prepared to buy and hold. It is not ok for individual stocks. For me personally, I will use Tiger to buy ETFs which I am prepared to hold for the long-term as a start. The probability of Tiger going bust is low at this point in time(Aug 2020) thanks to a strong balance sheet with long-term debt negligible compared to short-term assets alone and short-term assets exceeding short-term liabilities. However, Tiger is exposed to the dangers of financial markets because Tiger extends margin credit to her brokerage clients. A black swan event can cause clients to blow up and the financial contagion can spread to the broker. Due to these risk considerations, I will use Tiger as a back-up broker for the time being despite being very satisfied with their platform. I sincerely wish every success to Tiger Brokers but as investors, we had better consider all these risks first before we commit our funds to any party.
One aspect that I dislike about Tiger's platform is the lack of configuration options for the software. For example, I find the dark mode in the desktop app too dark. The fonts are too small and it strains my eye to use Tiger platform after some time. This is actually a serious user problem.
If any staff from Tiger is reading this, could you allow the user to configure the font size and color? If not, please at least use a brighter red color by default in dark mode for your desktop app. The current red color looks dim in dark mode and is eye-straining to look at.
