how can I do to put a sell limit pending order? can I have an example?

Dear Friends,

pls note i want to create new EA

that works like

i want it to open SELL order if not any open position
and then if market go down X pip then it open another sell with X multiple(2 or 1.5 or 1 or 0.5) and put SL off ALL SELL position X pip above the last SELL trade
it will repeat same thing to X number of maximum-trade.

if once clear all trade then same SELL will open and repeat same thing. and if market go up X pip it will hit SL

Same thing for BUY also but it should ask for Allow BUY or Allow SELL

and pls make sure i will work in both 4 digit and 5 digit broker

how to make a trade at the same price if you ever stopped?
seems absurd to me that there is nobody who can help me?

can you tell me how can I do to create an expert advisor that when I open a position and close to me, forgive my stop loss 50 pips a ordinependente the price of the previous location?

Someone may help me to solve this problem?. I can try to explain by an example :
I open the fxdreema program and insert a new position BUY at the price now : 1.3050 with stop loss 1.3030 (up this point is ok : no problem).

IMMEDIATELY (not after) I want insert a pending order at the same price 1.3050, in the case of the previous order to be closed at 1.3030 by stop loss : IS POSSIBLE OR NOT???

And is possible that at the price of 1.3050, to be AUTOMATICALLY open a buy order every time the order will be closed at 1.3030 by stop loss? Which is the block (the format) in FXDREEMA?

Thank you very much again in advance for your kind and important cooperation.
