I need a Pine script indicator that matches my strategy

I need an indicator that will help mark the previous candle equilibrium thats from the high to the low and mark my mid spot as the equilibrium but the half of the candle to be marked as a tspot with the flexibility of changing the tspot color box. The previous candle equilibrium i should have the option to either choose my higher  timeframe of choice that aligns with my lower timeframe entry timeframe. That is if i choose my higher timeframe to be 1H - the lower timeframe should be the 5m or lower anything abover the 5m and my choice if higher tf being the hourly should display an error. So the tf are as follows 1M - 1D, 1W - 4H, 1D - 1H, 4H - 15m, 30m - 3m, 15m -1m, 5m - 15s. Now the candles should display the eq at anytime but should display Change in state of delivery whenever we have a sweep of previous higher tf candle and closes below. After the close on the respective lower tf candle a series of candles of the opposite direction after the sweep are considered cisd but from the body and not the wick where now it marks me my CISD. I will share a similar indicator that works the same with the settings. And to add to it can i have alerts of the htf candles that dont close below previous candle to show a potential setup is about to happen. In simple terms should alert on potential CRT candles

A similar indicator is on the video screen record shared on the link https://files.fm/u/q9hs9cevuf
