App/Web responsive Autotrader app

This app will have 2 types of cryptocurrency trade signals coming in: (1) From tradingview in the form of webhook responses (2) Custom designed strategies that are designed and built-in to the web hosted mainframe which execute signals to connected user brokers via broker api. The autotrader should be able to: set TP, SL, Group TP, Trailing stops (all types based on value or percentage), calculate required balance (in the case of grid systems). The UI should have a charting package that allows for viewing of each pair and the trades that have been executed. Server-side setup and app should exhibit low-latency commands to execute limit/market orders instantaneously to avoid slippage. The backend needs a user db with 2fa utilizing sms and google authenticator (optional). The app will need 2fa with sms and google authenticator (optional). Currently there are 2 strategies that need to be implemented. The first is a tradingview strategy and the other is a strategy the dev will need to implement, test (in exchanges sandbox environment) and code into the server backend. Other strategies will need to be added later which will require a rehire for small additions to the app.
