Simple MT4 EA Required Urgently

Initial entry (“initial trade”) is manual and a take profit is set at N pips. 
Note: My objective in this strategy is to trade with the trend. I enter the trade in the direction of the trend when the GREEN line crosses the RED line in the Alligator (13, 8, 5) Indicator on the 1-Day Chart. This is a very simple indicator so I’m sure there is plenty of room for improvement and I am open to suggestions! Once the initial trade is executed, I would like the system to set follow-on trades automatically as follows: General:
 If initial trade is a BUY, all follow-on trades should also be BUY and vice versa.
 As long as the trend continues (i.e. the GREEN line hasn’t crossed BACK over the RED line in the Alligator (13, 8, 5) Indicator on the 1-Day Chart since the initial trade was executed), follow-on trades should be set automatically every N pips (by default this should be the same number of pips as the take profit in the initial trade, but it should be adjustable).
 A take profit should be set automatically for each follow-on trade at N pips (by default this should be the same number of pips as the take profit in the initial trade, but it should be adjustable).
 If price moves with the trend: 
 Follow-on trades should EXECUTE immediately when reaching N pips.
 Example N = 300. Suppose the initial trade was a BUY at 1.37600 with a take profit at 1.37900. The price increases to 1.37900 where the initial trade closes based on the take profit and the follow-on trade automatically executes with a take profit of 1.38200. The price continues to increase and when it reaches 1.38200, the first follow-on trade closes based on the take profit and a second follow-on trade automatically executes with a take profit of 1.38500. And so on… until the GREEN line crosses BACK over the RED line in the Alligator (13, 8, 5) Indicator on the 1-Day Chart, and no further follow-on trades should automatically execute. If price moves in opposite direction to trend:
 Follow-on trades should be SET once the price reaches N minus V pips when setting BUY trades or N plus V pips when setting SELL trades (default for V should be 30 pips but it should be adjustable) and the trade should only EXECUTE at N pips “on the way back”, i.e. once the price is moving in line with the original trend again.
 Example N = 300 pips. V = 30 pips. Suppose the initial trade was a BUY as per the example above. After the second follow-on trade was executed at 1.38200, the price continues to rise to 1.38400 and then reverses and starts moving down. It passes 1.37900 and when it reaches 1.37870, a third follow-on trade is automatically SET at 1.37900 with a take profit of 1.38200. The price continues to fall and as it reaches 1.37570, a fourth follow-on trade is automatically SET for 1.37600 with a take profit of 1.37900. The price continues to fall and reaches 1.37500 where it reverses and starts to move upwards again. When it reaches 1.37600 the fourth follow-on trade automatically EXECUTES. The price continues upwards and when it reaches 1.37900, the fourth follow-on trade closes based on the take profit and the third follow-on trade automatically EXECUTES. And so on… until the GREEN line crosses BACK over the RED line in the Alligator (13, 8, 5) Indicator on the 1-Day Chart, at which point no further follow-on trades should be set automatically. Money / Risk Management:
 Stop losses to be set manually if preferred.
 Lot sizes of trades that are set automatically should be the same as initial trade by default but it should be adjustable. Exit:
 Trades will usually stay open until they reach stop-loss but if necessary they will be closed manually. The use of a stop-loss is not preferred.
