Stop Loss feature

[bludnic]

Some exchanges support native stop loss https://docs.ccxt.com/#/?id=stop-loss-orders

Since not all exchanges have support for native SL, we need a configuration for each connector to handle the SL on the bot side:

class Exchange {
  features = {
    // One cancels the other: 
    // - Entry order handled by the bot
    // - Exit order (TP + SL) handled by the exchange
    oco: true,
    // Same as above, but entry order is also handled by the exchange
    ocoAttached: true, // Entry order + OCO (TP + SL)
    // If OCO is unsupported, we can use StopOrder. However, only one order can be placed at a time (due to locked funds), 
    // either TP or SL. Workflow: Place SL order immediately after entry, then monitor the ticker. Once the price nears TP, 
    // cancel SL and place the TP order.
    stopOrder: true,
    // If neither OCO nor StopOrder is supported, TP and SL must be managed on the bot side.
    // Simulate the Stop order for SL: monitor the ticker, and when it hits the stop price, place the SL order on the exchange.
  }
