I am looking to see if any trading platforms out there offer advanced trading techniques, specifically conditional orders. For example, if I have an open buy limit order for a cryptocurrency that would buy at a dip/support level, I would ideally like to automatically place a conditional secondary order (which would be a sell limit order) to be issued if and only if the first order (the buy limit order) of this trade pair is executed. That 2nd order would be a sell limit order to sell the units just purchased in the first leg of the trade, for a profit. Right now, I do this manually, i.e., I manually enter a new sell limit order after a buy limit order is filled, and it works fine, but if I'm away from the market for long periods of time, there are missed profit opportunities in wildly swinging markets which could be avoided with this type of order conditionality. Right now, I use Coinbase Advanced and I don't believe this functionality exists, having looked into it and examined both Stop Limit and Bracket order types.
