Create a simple Triple Exponential Moving Average EA

I am interested in an EA which uses a simple triple EMA for GBPUSD pair, although theoretically this could work on other currency pairs and commodities etc.

 This should function in both MT4 & MT5.

The method I have in mind is as follows:

• Plot three exponential moving averages—a five-period EMA, a 20-period EMA, and 50-period EMA—on a 15-minute chart.
• Buy when the five-period EMA crosses from below to above the 20-period EMA, and the price, five, and 20-period EMAs are above the 50 EMA.
• For a sell trade, sell when the five-period EMA crosses from above to below the 20-period EMA, and both EMAs and the price are below the 50-period EMA.
• Place the initial stop-loss order of 10 pips from the entry price (but can be set by user).
• Place a profit target of 20 pips from the entry price (but can be set by user).
• The tick size is set to 0.25% of the funds available, with a minimum of £0.50 and a maximum of £2a r (all of which can be set by user).
• Any open trades should close on a Friday evening so that nothing is left open over the weekend.
• There should be a risk  parameters and hourly start and end trades functions.
• EA should be able to stop trading when hit take profit % which can be set by user
• EA Should be able to PASS Prop Firm Challenge Account and trade on live account after..

Thank you very much. I should hope that this is all the required information.
