Ninjatrader strategy development

The strategy should buy a futures contract at market Ask price. The contract should be held until the price reaches its highest point since entering the position. A user specified virtual (does not show on the order book) trailing sell stop should be in place so when the market begins to decline it activates. It would be excellent if I could have the option of a fixed virtual stop or be able to click variable virtual stop. The tick levels for the virtual stops should be 1 - 3 ticks. When the position is flat it should immediate enter a short contract, holding the same number of contracts accumulated while long, with a virtual buy stop in place. It should then switch back and forth between long and short positions based on the direction of the market. The system should have the ability to start with 1 or more contracts and scale into additional contracts based on the user specified incremental increase increase in account value. If the market/notional value decreases be a user specified percentage, trading should be halted for 2 minutes (It would be great to get an alert). I’ll need the ability to enter tick value for US Treasuries. Therefore I’ll need enough decimals, unless you can insert combination boxes that automatically select tick size based on the contract. Lastly, not all contracts trade the same. So, I’d like to enter a user-specified (0 - 10 ticks) “buffer” zone where the code doesn’t implement the virtual stop unless the current bid/ask is the specified number of ticks away from the long/short contract entry price.
