program a trading system to pine script on trading view

Hello, I am needing a trading script programmed on PINE SCRIPT on Tradingview.com. It is a simple system, with a few simple rules. The layout. I use RENKO bars, not candles. I need to be able to change the settings of the Renko, sometimes the default ATR, but for some markets, I want to select my own number, like 50 or 100 pips/points. I need 2 Hull Moving Averages with the system which need to have an option to change the value of. I need to select a period of time for backtesting purposes, 01/01/2010 - 31/12/2019 The conditions. There is always a trade on, the question will be, which direction? The entry condition is the the exit condition for an existing trade. To go long, or exit a short position: The last Renko bar must have closed higher than the previous one, eg a new green bar. Both Hull moving averages must be pointing up and showing green. To go short, or exit a long position: The last Renko bar must have closed lower than the previous one, eg a new red bar. Both Hull moving averages must be pointing down and showing red. There is no stop loss or take profit associated with this system, but I do need one as a precautionary measure, modifiable and viewable on the chart. This will be set at a distance so far away that it will probably never be triggered, but it needs to work. The system will be trading on a live account through the trading view signal service, probably linked to forex.com. Position sizing needs to be modifiable. Either I select a position size or I select a percent of equity. I must be able to see on the chart, what the system is doing and when. I think that I have covered everything for this system, however you may have questions about it, please feel free to contact me about it. Cheers. Steve.
