I need someone who have experience in Tradingview

I would like to have a strategy in pinescript that I can backtest for several other stocks and shares. I was wondering if you could help me program the strategy. So the strategy is for only dividend paying companies. The basic is quite simple: The strategy buys the particular stock x days before the ex-dividend day and sells it the day before. E.g.: buys CVX stock 9 days before the ex dividend date and sells it the day before the ex div date. The strategy buys the stock at the opening price of the 9th day before the ex div date and sells the stock at the opening price one day before the ex dividend date. The logic behind it, is that for UK higher rate taxpayers they will only pay the capital gains tax but not the dividend tax. (I know that the strategy works in real life, I have been doing that for many years now, but I would like to test out the best scenarios). I would like to test the strategy for several stocks and also with some scenarios: I would like to have a stop loss programmed into it which I can change as a percentage from the entry price. As a default it can be 5% stop loss. In addition, I would like to test what happens if the stock is sold at the opening or the closing price the day before the ex dividend date. I would also like to test out what happens if the stock is sold after the ex dividend date so the closing date could be moved forward after the ex div date. In terms of ex div dates, as far as I know the pine cripts knows them, I fould a link to that: https://stackoverflow.com/questions/74250093/entering-a-strategy-x-days-before-ex-date Let me know if I explained the basis of the strategy well and if you can help me program it
