I would like to create a stoploss order that will be placed above the high of the previous order's initiation bar in case this is a Sell order OR below the low of the previous order's initiation bar in case this is a Buy order.
Here is a picture to illustrate the issue ( the example depicts a sell order case ):
Any idea how to do that? The code below works fine if I use stoploss that is fixed. If I replace the stoploss with variables that are based on High or Low no orders are fired.
Here is my code:

Major issue
Once having assigned ( per each Market Event Quote Arrival )
double HH = High[1],
LL = Low[ 1];
Your instruction to OP_SELL shall be repaired:
ticket = OrderSend( Symbol(),
OP_SELL,
Lots,
Bid,
10,
// ----------------------v--------------------------------------
// Ask + HH * 10 * Point,
// intention was High[1] + 10 [PT]s ( if Broker allows ), right?
NormalizeDouble( HH + 10 * Point,
Digits // ALWAYS NORMALIZE FOR .XTO-s
),
// vvv----------------------------------------------------------
// Ask - TakeProfit * Point * 10, // SAFER TO BASE ON BreakEvenPT
NormalizeDouble( Ask
- TakeProfit * Point * 10,
Digits // ALWAYS NORMALIZE FOR .XTO-s
),
"Set by SimpleSystem"
);
Symmetrically review and modify the OP_BUY case.
For Broker T&C collisions ( these need not get reflected in backtest ) review:
MarketInfo( _Symbol, MODE_STOPLEVEL )
MarketInfo( _Symbol, MODE_FREEZELEVEL )
or inspect in the MT4.Terminal in the MarketWatch aMouseRightClick Symbols -> Properties for STOPLEVEL distance.
Minor Issue
Review also your code for OrderClose() -- this will fail due to having wrong Price:
// ---------------------------------------------vvvvv----------------------------
bool res2 = OrderClose( ticket, Lots, OrderClosePrice(), 10 ); # was db.POOL()-SELECT'd
