EA or Script to semi automate trade exectution with SL + TP

I am not sure if i need a script or an EA.

What im looking for is a semi automation to a currently manual process in my trading. After a specific point/level within a market maker cycle there is a exponential moving average cross over of 50/200 04 200/800 after which price will pull back to 200ema or 800 ema respectively before continuing in original direction to complete the market maker cycle. This should not be fully automated as the strategy only works in a certain part of the cycle. During a peak low or high price tends to chop for a few days to weeks with volatile swings in which many false signals will be given where the ema's flatten out.

To avoid this i still will monitor the forex pairs manually to establish the right timing. Once the correct part of the cycle is established and the moving averages have had the cross over i want to drop the EA/Script into the chart so i dont have to monitor the timing of the pullback in order to participate in the trade opportunity.

i would like some some inputs to modify based on volatility of market conditions and different forex pairs, as well as lot size, risk %, SL pips, TP pips, WHETHER ITS 50/200 OR 200/800 EMA's involved, whether limit order is placed on the ema line or certain amount of pips behind it, and lines on chart for SL & TP that can be dragged after the trade is live to manually trail the stop and to modify the TP if necessary.
