Costs to develop a strategy in tradingview(pine script) for back testing and possible future use

5 min candle strategy for GOLD
Conditions
1. if 7 am candle closes green- 1 point goes for the trade to be a sell. if candle closes Red- 1 point goes to trade being a buy
2.Which Wick (top or bottom) on 7 am candle is larger- if wick is larger on top- 1 point towards sell, if larger wick is bottom- then 1 point towards buy
3. Short term trend- in the past 5 candles is the trend up? if so 1 point towards a sell. if the 5 candle trend is down then 1 point towards a buy. Yes countertrend....
4. support and resistance- at the specific 7 am candle is there a support or resistance area close by- if closer to the top of 7 am candle 1 point towards a sell. If a support area is closer to the bottom than top 1 point towards

publish the point count above and or below the 7:05 candle

also need this for automated back testing
conditions- if 3 points or more for either direction take trade 500 pip Stop loss (aka $5 in gold), at 600 pips move take profit to 500, at 800 move tp to 700, at 1000 move tp to 900, so on and so forth.


if it's a tie 2-2 weighted so the support and resistance factor does not come in play- example 7 am candle is green, the 5 candle trend is green(up), the biggest wick is on the bottom and the support is closest to the bottom scoring 2-2- this trade would be a sell.

I'm looking for a general cost to create this?
