Auto set take profit EA

I need to create an EA that sets take profit automatically for the trades i place manually,

• I usually open buy and sell trade at same time and set a fixed TP for each, e.g. 10 pips.
• When one side of trade in drawdown, i will open additional trades and at this time, EA should set the TP based on the average price.
• e.g. when i open one buy trade EURUSD at 1.1200 and another one at 1.1170, the average is 1.1185, if my setting in EA is 10 pips, then the EA should modify the TP at 1.1195 for both trades.
• EA should be able to calculate different lot sizes. e.g. 1.0 lot at 1.1200, and 2.0 lot at 1.1170, the average should be ((1.1170*2)+(1.1200*1))/3 = 1.1180, and EA should auto change tp to 1.1190 for all trades.
• EA should operate buy trade and sell trade separately, do not conflict each other.
• EA should work for only the symbol that EA is on the chart.
• EA should detect all trades placed manually, i use both mobile and MT4 terminal to place trades.
• EA should detect only open trades, should not consider pending trades that are not open yet.

• Important: EA should be able to recalculate average and apply correct TP when there are trades closed. I sometimes will close some trades in profit.
• e.g. when there is 5 EURUSD buy trades open, at 1.1200, 1.1180, 1.1160, 1.1140, 1.1120. And now price of EURUSD is 1.1170, I sometimes will close some of the trades in profit individually,
• in this case, EA should set TP according to the remaining open trades. e.g. 1.1200 and 1.1180 trades left, EA should immediately change TP based on these two trades.
• Therefore, EA should update at least once when there is new trade, when there is trade closed, etc.

• EA should have display of total buy profit/loss and total sell profit/loss on the chart, and display a close all buy trades, close all sell trades, and close all trades, 3 buttons.
• The final product send to me should be include source file so I can further modify in the future if need.
