The problem TradeArena solves

All the 3 team members of the revered TeamOne are competitive coders and have been doing that for quite some time now. Two of the members have been trading actively in the Indian Stock Market, when solving problems on HackerRank my main motivation came by seeing that my friend had more points than me and I’ll have to pull an all nighter to surpass him, this is the one thing that we always missed in the trading domain. Hence we decided to make a simulator where we can conduct competitive trading leagues and maintain a healthy competition.

Challenges we ran into

The main Problem we faced was that we had to implement live rate updatesfrom the exchange, to make the feel of the virtual trading close to real trading. for that we basically built an API and would fetch the live data from NSE's website. Secondly we had to build a leaderboard that is updated in real time and for that we had to upgrade our DataBase systems, we did that and accomplished the goal and were finally running a dynamic leaderboard.
