Exit EA - TDI

I want to make an EA out of it. it is easy. Here are the things I want as parameters in the EA. This EA has to detect few things first. 1. Detect that trade has been taken on the currency. (I am going to apply this EA on all the currencies, so make sure it detects the trade of the currency it is applied on) for eg. This EA has been put on 4 currencies. And out off which I take trade on GBP CHF. So it detects that and turn itself on only for that currency. 2. Second thing it needs to detect is that if the trade is sell or buy 3. Third thing it needs to detect is the time frame. Now for the parameters (then i will explain them below them) 1. Green Cross Red Alert on/off (this alert needs to come when green line crosses red. So if the trade is in buy, then i need to know when green crosses, so basically it detects when value of green has gone below the value of red. And for sell, it sends the alert when value of green has gone above the value of red) 2. Green Cross Yellow on/off (Same thing as above) 3. Green cross 50 on/off (Fro eg if i have a buy trade, and the value goes below 50 it sends me an alert, and for sell trade if the value has gone above 50 it sends an alert) 4. Refresh time - in minutes Things to make sure. 1. The alert is only sent for the currency on which trade is placed. 2. The alert is sent at the start of the candle of the time frame on which EA is placed. 3. Once the alert has been sent, it sends the next alert at the next candle, if the trade is still going. 4. Now if all the alerts above are put on, then it first sends me whichever becomes true, and if the trade is still going it sends me the next one, and keep going until the trade is going. 5. Once the trade has been closed, it shuts off automatically. Contact me if any questions. I am student so the budget is between 25-30 dollars.
