Help me make an EA more orders

I need an expert advisor to place additional orders when the price moves against my own. and if the initial price is in the right direction, only the trailing stop is the first order and no additional order is required
for example: I buy EURUSD at 1.12000 and if the price goes up to 1.12100 the trailing stop follows the price going up. Unfortunately, if the price goes down to 1.11900, an additional buy order will be placed at 1.11900, and if the price goes down to 1.11800, an additional buy order will be placed at 1.11800, and if the price goes down to 1.11700, an additional buy order will be placed at 1.11700. and so on … and let it work on all pairs
Please, give me the expert advisor as above. I just thank you guys
