A risk meter icon or clock have to seen on top of trading screen. which is based on percentage use of total capital in trades in single direction I.e. either call or put. Also show high risk as we using capital more than 25 percent of total capital in one direction. This risk meter also linked exponentially to time remaining in expiry. If this will shown on our screen, we never take risk of total capital in single direction. and I assure, it will reduce big loss of capital of max. traders.
