Chart Studio codes 2 crossing moving average strategy

Dear Sirs, Hereafter is the code. I am looking to be constantly exposed: LONG than SHORT than LONG again etc... input Ema_period1 = 5 , Ema_period2 = 10, open_position_as = 1, // only open a position in the direction you want // 1 = buy & 2 = sell - any other number will not work lots = 1; // amount of open positions to be closed ; vars ema1(series), ema2(series); begin ema1 := EMA(close,Ema_period1) ; ema2 := EMA(close,Ema_period2); if crossup(ema1, ema2) then begin if open_position_as = 1 then buy(lots); end; if crossdown(ema1, ema2) then begin if open_position_as = 2 then sell(lots); end; end. I do not know where to fix the following. **"You can reverse positions in CTL. For example:"** **if (conditions) then begin** **if short() then exitshort();** **buy(1);** **end;** **This would close any short position and open a new long position for 1 lot. Alternately, to reverse a long position to short:** **if (conditions) then begin** **if long() then exitlong();** **sell(1);** **end;** ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
