Create EA to trade custom indicator rectangles alongside other rules

I'm looking to develop an EA that allows me to trade rectangles that are created in a separate indicator called II_supdem; this indicator generates rectangles that are used to define possible risk and targets on a trade, For specific order levels I have specified a number of pips to enter orders above or below the supdem indicator objects, the risk for all trades and therefore the lot size for each half of the trade, and all target calculations are all based on this - so it is important The trading EA it trade them based on a simple rule of only entering trades at the supdem levels when prices are outside of the 2.5 std deviation 20 period ma bollinger bands EA Inputs i) Pip Value = to specify what a 'pip' is, this is crucial to calculate everything correctly - including entries, stops, targets etc ii) Position size per trade = 1.0% default (this is to be split into two equal trades) iii) Target 1 = based on preset reward to risk ratio (default 2.0x) iv) Target 2 = based on a multiple of the average true range (ATR) (default = 3.0x) being a volatility based target v) Buy order number of pips above rectangle = (default 3.0 pips) + spread above the supdem level vi) Buy order number of pips below rectangle = (default 1.0 pips) vii) Sell order number of pips below rectangle = (default 3.0 pips) viii) Sell order number of pips above rectangle = (default 1.0 pips) + spread above the supdem level ix) Bollinger band moving average period = (default 20) x) Bollinger band standard deviation = (default 2.5) xi) Average true range (ATR) period = (default 14) xii) Trail stop (target 2 only) = move stop loss to 5 pips above or below entry once target 1 is hit xiii) Minimum number of pips risk = (default = 10) to avoid trading very small levels xiv) Maximum number of pips risk = (default = 300)) to avoid trading very large levels This EA needs to be able manage the following: 1) Be able to determine what a 'pip' is, based on the currency, also taking into account brokers that use fractional pips (1/10th pip) adding another decimal point 2) Be able to determine position sizing for each trade based on a % account equity at the time of entry i.e. 1%, but also be able to split this amount into two separate halves of the same trade These two halves of the trade will have the same entry and stop loss but have targets based on different criteria (i.e. 1st half of trade based on variable reward to risk ratio, 2nd half based on ATR multiple) 3) Be able to round all positions down to the nearest 0.01 lot, with the minimum order being 0.01 lot ($1000 micro lots) 4) Be able to trade both long and short 5) Ensure that all trades have a fixed stop loss placed immediately upon entry (no naked positions) and preset targets for both halves of trades 6) Only trade a rectangle level once, even if prices return to the same rectangle again in the future 7) Be able to trail a stop loss on the second position of a trade only - only after the first target is hit, then the stop loss is raised to 5 pips above entry (for long trades) or below entry (for short trades) 8) It is important to use only the first rectangles nearest current market prices for possible long or short entries and these must be based on the external indicator, the reason is I would like to modify the indicator in the future to clean up (remove) unnecessary rectangles that it creates 9) Only trade the levels where prices reach the supdem level while outside of the 2.5 std deviation bollinger bands Any questions please ask, please note all bids should be in NZD
