Tradingview Pine script to trigger & manage spreadbetting trade

I am testing a few speadbetting strategies on some indices. I am using tradingview and use a MAC computer. 1. At a specified UK time, check where Index closed previous trading day, 2. At a specified UK time, compare today’s opening price with the previous day’s closing price. 3. If there a minimum gap of a specified number a trade will be opened based on the entry criteria. 4. If the opening price is lower than previous closing price, a SELL spreadbet trade will be opened to close the GAP if the entry criteria are met. 5. If the opening price is higher than previous closing price, a BUY spreadbet trade will be opened to close the GAP if the entry criteria are met. 6. Wait for the 1st 5 min bar to complete. 7. The size of the spreadbet point will be specified. Entry Criteria for a BUY trade Place an order to trigger if the price then penetrates the high of the 1st 5 min plus an extra number of specified points Entry Criteria for a SELL trade Place an order to trigger if the price then penetrates the low of the 1st 5 min minus an extra number of specified points Stop Loss Place a stop loss of a specified number of points from the entry point Adjustment Rules At a specified time, check and do one of the following: a) If the trade has not been triggered, change the stop to a specified number of points. b) If in profit by a specified number of points, move the stop to lock in a specified % of profits. c) If in profit of less than a specified number of points, move the stop loss by a number of specified points. d) If in loss of greater than a specified number of points, and in a BUY trade, move the stop to the LOW of the 1st 5 min bar. e) If in loss of greater than a specified number of points, and in a SELL trade, move the stop to the HIGH of the 1st 5 min bar.
