Amibroker Stratergy coding

I require someone to write a trading strategy in Amibroker and also provide some brief instructions on how to change the parameters. The strategy is from the book 'Stocks on the move' by Andreas Clenow. The screening category: Index (SP 500) above 200 moving average Stock above 100 moving average No gaps in stock larger than 15% in the last 90 days Stock Ranking Annualized exponential regression slope calculate on the last 90 days, multiplied by the coefficient of determination Position Size Account value * 0.001/ average true range (20) Buying stocks that pass the screen and rank the highest, working down the list until the money runs out. Rebalance once a week. Sell stocks that are no longer in the top 20% of the ranking list or that do not match the sreening ie not above 100 moving average. If index (SP 500) below 200 moving average, do not buy any new stocks. [login to view URL] Thanks
