Make PineScript Strategy using custom Indicator

I have a custom Indicator that plots swings. I would like a fairly simple strategy written that opens a single trade when the swing hits either swing high or swing low. Once the initial trade is open a stop loss is placed on the opposite swing. The trade take a percentage profit after a set amount of pips. The stop loss is moved up when new swings are made. The trade opens position sizes based on a percentage of the total asset calculated by the stop loss distance.
