Add option to show $ gain/loss with TP and Stop orders on chart

The position indicator on the chart has the ability to show up to date P/L. ATAS should also have the option to illustrate projected gain/loss next to each TP and stop order, reflective of the number of contracts that order is removing. For example, if TP1 takes off 2 contracts - the $ gain for those 2 contracts is shown next to the limit order on the chart. If TP2 takes off another 2 contracts further up, then the $ gain for those 2 contracts is shown next to that order.
